Suppose that an object travels from one point in space to another. Make a comparison between the magnitude of the displacement and the distance traveled by this object.

Answer:

A beta emission(negatron)

Explanation:

1. A negatron resembles an orbital electron. It is represented as β⁻.

A negatron has a mass number of 0 but with a charge of -1

The decay of C-14 to N-14 can be depicted below:

¹⁴₆C → ¹⁴₇N + ₋₁⁰e

Both the mass number and atomic number is balanced according to the reaction.

2. In an electric field, the emission produced would be deflected towards the positive pole because it is negatively charged.

Beta radioactive emission

During this radioactive decay, Beta charges are released. These negative particles tend to be attracted to the positive plate in the electric field.

The radioactive decay of C-14 produces a N-14 atom through the emission of Beta particles.

The Beta particles are negatively charged and would be attracted to the positive plate in the electric field because according to law of charges, like charges will tend to repel each other while unlike charges will attract each other.

The amount of heat [tex]Q[/tex] absorbed in the temperature variation of a material is:

[tex]Q=m. c. \Delta T[/tex]   (1)

Where:

[tex]m=435g[/tex]  is the mass  of water

[tex]c[/tex]  is the specific heat of the element. In the case of water [tex]c=1 cal/g\°C [/tex]

[tex]\Delta T[/tex]  is the variation in temperature, which in this case is  [tex]\Delta T=100\°C-25\°C=75\°C[/tex]  

(The boiling point of water at the pressure of 1 atm is  [tex]100\°C[/tex])

Rewriting equation (1) with the known values:

[tex]Q=(435g)(1 cal/g\°C)(75\°C)[/tex]  

(2)

[tex]Q=32625 cal[/tex]   (3)

Nevertheless, we are asked to find this value in Joules. So, we have to convert this 32625 calories to Joules, knowing the following:

[tex]1 cal=4.187 J[/tex]   (4)

Hence:

[tex]Q=32625 cal=136600.875 J=136.6kJ[/tex]

I'll have to be honest with you.  I've read both of those opinions several times, carefully, and it looks to me like both technicians are saying exactly the same thing.

Now, my knowledge of shims and camber is limited (to approximately zero), so all I can say to answer the question is this:  If EITHER technician is correct, then they're BOTH correct.

Shims are used to adjust camber, not caster.

Technician A is correct. Shims are sometimes used to adjust camber in vehicles. Camber refers to the angle of the wheels relative to the vertical axis when viewed from the front or rear of the vehicle. Shims are thin metal or plastic pieces inserted between the suspension components and the vehicle frame to adjust the camber angle.

Technician B is incorrect. Shims are not used to adjust caster in vehicles. Caster refers to the angle of the steering axis when viewed from the side of the vehicle. Caster is typically adjusted by changing the position of the control arms or using adjustable suspension components.

Atoms and elements are pure substances.

Elements are pure substances made up of one type of atom. Atoms are the smallest unit of an element and include protons, neutrons and electrons. The number of protons in an atom defines the element it represents.

The relationship between atoms and elements is foundational to the study of chemistry. Elements are pure substances that consist of only one type of atom. For instance, the element gold is made up of only gold atoms, and the element oxygen is made up of only oxygen atoms.

Atoms are the smallest unit of an element that retains the properties of that element. They are composed of protons, neutrons and electrons. The number of protons in an atom determines the element it represents. For example, an atom with one proton is a hydrogen atom, whereas an atom with six protons is a carbon atom.

The downward force of your weight on the floor and the upward force of the floor against the bottom of your shoes are an action-reaction pair.

Those two forces against the soles of your shoes are equal and opposite forces.  If they were not equal and opposite, then they would add up to something that would not be zero.  There would be some NET force there, and the soles of your shoes would be accelerating up or down.  Since they're NOT doing that, and you're just standing there motionless, there can't be any net force there.  Those two forces must exactly add up to zero.

Answer:

two forces such as weight and normal that are in the same body are not the force of action and reaction

Explanation:

Newton's third law says: "If two bodies interact the force exerted by the body 1 on the body 2 is of equal magnitude and opposite to the force exerted by the object 2 on the 1"

Let's analyze this sentence in our case, the bodies are the Earth and the chair

The Earth pulls the body creating its weight at the same time the body pulls the Earth, with an equal force, notice that each force is applied to a different body, so they cannot be added. These are forces of action and reaction

The chair does not accelerate due to its weight because it is supported by the floor, but it creates a very small deformation that creates a response called Normal force to this support, applied to the chair. The force of the deformation is applied to the floor. These are forces of action and reaction.

Therefore two forces such as weight and normal that are in the same body are not the force of action and reaction

When light strikes a red object, the light waves of all colors except red are absorbed into the object, and never heard from again. (B)

The only thing left to bounce off of the object into anyone's eye is the waves of red.

When light strikes a red object, the light waves of all colors except red are absorbed. The correct option is B.

The light is the ray form of energy which falls on the object to enlighten them and make us able to see that object.

Answer:

B

Explanation:

Friction acts in a direction opposite to the motion of an object

Friction force acts in a direction opposite to the intended motion of an object. It depends on the coefficient of friction between the surfaces and the normal force exerted in response to gravity.

In understanding the principles of Physics, the correct description of a friction force is that It acts in a direction opposite to the motion of an object. This phenomenon can be illustrated in several scenarios, such as a box sliding across a floor or objects moving on an inclined plane. In both cases, the friction force always opposes the motion of the object.

For instance, if a box is being pushed to the right, the frictional force works to the left. If an object has a component of its weight pulling it down an incline, the frictional force acts upward on the incline, opposing the intended motion.

It's important to note that the force of friction depends on two factors: the coefficient of friction between the two surfaces and the normal force exerted by the surface supporting the object in response to gravity. Furthermore, friction runs parallel to the surface between objects and perpendicular to the normal force.

Answer:

E) 1500 N

Explanation:

The total height from which Santa has fallen down is

h = 9 m + 2 m = 11 m

So its gravitational potential energy at the beginning was

[tex]U=mgh=(120 kg)(9.81 m/s^2)(11 m)=12,949 J[/tex]

While sliding down, Santa has lost all its gravitational potential energy: this energy has been converted into thermal energy due to the presence of the friction. So, the work done by friction is exactly equal to the initial potential energy of Santa:

[tex]W=12,949 J[/tex]

The work done by friction is

[tex]W=Fd[/tex]

where

F is the force of friction

d = 9 m is the length of the chimney (the distance through which the frictional force acts)

Solving the equation for F, we find

[tex]F=\frac{W}{d}=\frac{12,949 J}{9 m}=1439 N[/tex]

So the closest option is

E) 1500 N

Answer:

640 J

Explanation:

The work done by the piston when expanding is given by

[tex]W=p\Delta V[/tex]

where we have

[tex]p=200 kPa = 2.0\cdot 10^5 Pa[/tex] is the pressure

[tex]\Delta V[/tex] is the change in volume of the gas inside the piston;

since we have

[tex]V_i = 0.2 L[/tex] is the initial volume

[tex]V_f = 3.4 L[/tex] is the final volume

The change in volume is

[tex]\Delta V=3.4 L-0.2 L=3.2 L=3.2\cdot 10^{-3} m^3[/tex]

and so the work done is

[tex]W=(2.00\cdot 10^5 Pa)(3.2 \cdot 10^{-3}m^3)=640 J[/tex]

Answer:

Supernova

Explanation:

A supernova explosion occurs when a high mass star ends its life cycle.

When a very massive star runs out of hydrogen used in the core for the nuclear fusion, it starts burning heavier and heavier elements (helium, carbon, etc.). However, this process stops when the star has burnt all elements lighter than iron: in fact, nuclear fusion of the iron cannot occur, since the process releases less energy than the amount of energy needed to start it. At this point, therefore, the star can no longer produce energy by nuclear fusion, and there is no longer any outward pressure that can counterbalance the gravitational force of the star, pushing inward: as a result, the star collapses under the action of gravity, and the outer layers "bounce off the core" producing a huge explosion called supernova.

The remnant of the supernova explosion is, depending on the mass of the star, a neutron star or a black hole.

Final answer:

Massive stars end their life cycle in a spectacular explosion called a supernova, with type II being associated with massive star collapse and type Ia with white dwarf explosions.

Explanation:

Massive stars terminate in a brilliant explosion known as a supernova. This explosion is one of the most spectacular celestial events and happens when a massive star collapses at the end of its life cycle. There are different types of supernovae, but the one caused by the collapse of a massive star is specifically called a type II supernova. Moreover, when white dwarfs explode due to gathering too much mass, they are termed type Ia supernovae, leaving behind no remnant. The death of very massive stars that do not explode in a supernova can lead to the formation of a black hole, adding another layer of complexity to stellar evolution.

Answer:

Explanation:

When two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies.

This is stated by Coulomb's Law:

"The electrostatic force [tex]F_{E}[/tex] between two point charges [tex]q_{1}[/tex] and [tex]q_{2}[/tex] is proportional to the product of the charges and inversely proportional to the square of the distance [tex]d[/tex] that separates them, and has the direction of the line that joins them"  

Mathematically this law is written as:  

[tex]F_{E}= K\frac{q_{1}.q_{2}}{d^{2}}[/tex]

Where [tex]K[/tex] is a proportionality constant.

Now, if [tex]q_{1}[/tex] and [tex]q_{2}[/tex] have the same sign charge (both positive or both negative), a repulsive force will act on these charges.

Answer:

0.687 m/s

Explanation:

Initial energy = final energy

1/2 mu² = mgh + 1/2 mv²

1/2 u² = gh + 1/2 v²

Given u = 2.00 m/s, g = 9.8 m/s², and h = 0.180 m:

1/2 (2.00 m/s)² = (9.8 m/s²) (0.180 m) + 1/2 v²

v = 0.687 m/s

The final speed of the toy car is about 0.687 m/s

[tex]\texttt{ }[/tex]

Let's recall Kinetic Energy Formula as follows:

[tex]\large {\boxed{Ek = \frac{1}{2}mv^2} }[/tex]

Ek = Kinetic Energy ( Joule )

m = mass of the object ( kg )

v = speed of the object ( m/s )

Let us now tackle the problem !

[tex]\texttt{ }[/tex]

Given:

mass of toy car = m = 100 g

initial speed of toy car = u = 2.00 m/s

initial height position of toy car = h₁ = 0 m

final height position of toy car = h₂ = 0.180 m

Asked:

final speed of toy car = v = ?

Solution:

We will use Conservation of Energy to solve this problem:

[tex]Ep_1 + Ek_1 = Ep_2 + Ek_2[/tex]

[tex]mgh_1 + \frac{1}{2} m u^2 = mgh_2 + \frac{1}{2} m v^2[/tex]

[tex]0 + \frac{1}{2}mu^2 = mgh_2 + \frac{1}{2} m v^2[/tex]

[tex]\frac{1}{2}u^2 = gh_2 + \frac{1}{2}v^2[/tex]

[tex]u^2 = 2gh_2 + v^2[/tex]

[tex]v^2 = u^2 - 2gh_2[/tex]

[tex]v = \sqrt {u^2 - 2gh_2}[/tex]

[tex]v = \sqrt {2.00^2 - 2(9.8)(0.180)}[/tex]

Answer:

radiated heat from the Sun being absorbed by the ground

Answer: radiated heat fron the Sun being absorbed by the ground.

Explanation: During the day the Sun is "shining", this means that the sun is "emanating" electromagnetic waves (some in form of visible light, this is why in the day we can see a lot of light) that reach us in the Earth. Those electromagnetic waves carry with a lot of energy, and when they impact the ground, they transmit that energy in form of heat. This "transmission" of temperature is called "radiation", so the correct option is the third one; radiated heat from the Sun is absorbed by the ground.

The Wright brothers, Wilbur and Orville, were pioneers of aviation, since they flew in a device heavier than air, which was inconceivable at that time.

Their first successful flight was on December 17th, 1903 in Kitty Hawk, North Carolina, which lasted only 12 seconds in which their plane (the Flyer I, with 341 kg, 6.4 m long and a wingspan of 12.3 m) traveled 37 m without touching the ground. This was achieved through the help of an external catapult that "threw" them into the air.

It should be noted that the Wright brothers only studied until high school, however, their passion for solving the problem of the human inability to fly, their perseverance and experience acquired over the years in their bicycle company, led them to reach that goal. An achievement that marked the beginning of the  aviation era.

Answer:

All this is due to atmospheric pressure (which decreases with height) and affects the boiling point of water. That is why for recipes that carry some liquid (cake or bread, for example) it is necessary to modify both the ingredients and the baking time.

To better understand this, let's begin by explaining that the boiling point of water at an atmospheric pressure at sea level is [tex]100\°C[/tex] and as the height increases and the atmospheric pressure decreases, this boiling point  will diminish, as well.

This means the water will not boil at the same temperature at different pressures, because at lower pressure the boiling temperature will be lower.

In other words, as at this point the water boils at a lower temperature, it heats less, so that the food takes longer to cook (because it is necessary to increase the cooking time in order to have a well done food).

This is because as the height increases, the atmosphere becomes drier, the air has less oxygen and moisture evaporates quickly, therefore, it is sometimes necessary to add more water to compensate this evaporation during cooking.

Hence, at higher altitudes, the cooking time will be longer.
