Intuition might tell us that rough surfaces on clothing would inhibit the speed of an Olympic athlete. Why is this line of thinking not true in some cases? How can controlled roughness actually promote speed?

Answers

Answer 1

The thinking that rough surfaces on clothing would inhibit the speed of an Olympic athlete may not be entirely be true in most cases because the drag that a person experiences is the effect of the air that he goes against and might not be affected by the clothing.

The controlled roughness may promote speed as this would allow the person for the proper ventilation allowing his system to work well by allowing air to enter.

Answer 2

Answer:

We associate roughness with a greater coefficient of friction, then we think that rough surfaces on clothing would inhibit the speed of an Olympic athlete. This is not always true because the amount of roughness might improve the way air pass through the fabric.

One example of controlled roughness that actually promote speed are the dimples on golf balls. Dimples create turbulence around the ball, which sucks air to the ball, making its displacement easier and promoting its speed.

Answers

Answer:

Cross contamination.

Step-by-Step Explanation:

The contamination that results from spread of bacteria from meat to vegetable is called cross contamination which means the bacteria from one type of food transferred to other food which eventually spoil the food.

This happens by direct contact of two types of food.

The contamination that results from the spread of bacteria from meat to vegetables is called Cross-contamination.

Cross-contamination is the movement of bacteria or other pathogenic microbes from one food item or surface to another, which can result in the spread of diseases.

In the case of meat and vegetables, cross-contamination can happen if bacteria from uncooked or carelessly handled meat come into contact with vegetables, either directly or through shared surfaces. This may occur while handling, storing, or preparing food.

Using separate cutting boards and utensils for raw meat and raw vegetables, washing your hands completely after handling raw meat, and storing meat and vegetables separately in the refrigerator are all critical ways to reduce the risk of cross-contamination.

Hence, the contamination that results from the spread of bacteria from meat to vegetables is called cross- contamination.

Read “Solar Basics” on the Energy Kids website. Specifically, read text under “Two limitations of solar energy”. Use the information to answer the question. What factors affect the amount of solar energy that reaches the Earth’s surface?

Answers

The amount of solar energy available varies by location on earth, the time of the day at that location, the season and weather conditions. Rain, fog, and clouds will lower the amount of solar power available to gather and there are fewer hours of sun available in different seasons (winter for North America). To gather solar power, you also need a large area. This can be lessened by conditions such as snow, so that even on a sunny day, covered panels will collect less energy.

Sample Response: The amount of solar energy that reaches the Earth’s surface depends on the weather, location, and time of year.

C. a lever is used to increase resistance force
D. a lever is used to increase the effort force

Answers

Which of the following is the reason a lever is used in a shovel?
D. a lever is used to increase the effort force

The figure shown below illustrates a lever being used to lift a weight W.
The applied force is F.

In order to lift the weight, the minimum applied force is
F*b = W*a
F = (a/b)W

When the ratio a/b < 1, then the applied force is less than the weight.
The principle behind the use of a lever is to keep the ratio a/b small in order to decrease the effort force.

Answer: A
A lever is used to decrease effort force.

Which object has elastic potential energy? a piece of bread a ball at rest a stretched rubber band a falling leaf

Answers

A stretched rubber band, for example, when someone stretches it and they let go of one side, it goes flying across the room.

A stretched rubber band has elastic potential energy.

An object is thrown with an initial velocity v0 forming an angle θ with an inclined plane, which a In turn it forms an α-angle α with a horizontal plane.

A) Find the distance X from the launch point to the point where the object falls. X = F (v0, θ, α, g)

B) Find the distance for v0 = 20m / s, θ = 53o , α= 36 ° , g = 9.8m / s2

Answers

Refer to the figure shown below, which is based on the given figure.

d = the horizontal distance that the projectile travels.
h = the vertical distance that the projectile travels.

Part A
From the geometry, obtain
d = X cos(α) (1a)
h = X sin(α) (1b)

The vertical and horizontal components of the launch velocity are respectively
v = v₀ sin(θ - α) (2a)
u = v₀ cos(θ - α) (2b)

If the time of flight is t, then
vt - 0.5gt² = -h
or
0.5gt² - vt - h = 0 (3a)
ut = d (3b)

Substitute (1a), (1b), (2a), (2b) (3b) into (3a) to obtain
[tex]0.5(9.8)( \frac{d}{u})^{2} -v_{0} sin(\theta - \alpha ) \frac{d}{u} - h = 0 [/tex]
[tex]4.9[ \frac{X cos \alpha }{v_{0} cos(\theta - \alpha } ]^{2} - v_{0} sin(\theta - \alpha ) [ \frac{X cos \alpha }{v_{0} cos(\theta - \alpha } ] - X sin \alpha = 0[/tex]
Hence obtain
[tex]aX^{2}-bX=0 \\ where \\ a=4.9[ \frac{cos \alpha }{v_{0} cos(\theta - \alpha )}]^{2} \\ b = cos \alpha \, tan(\theta - \alpha ) + sin \alpha [/tex]
The non-triial solution for X is
[tex]X= \frac{b}{a} [/tex]

Answer:
[tex]X= \frac{sin \alpha + cos \alpha \, tan(\theta - \alpha )}{4.9 [ \frac{cos \alpha }{v_{0} \, cos(\theta - \alpha )} ]^{2}} [/tex]

Part B
v₀ = 20 m/s
θ = 53°
α = 36°

sinα + cosα tan(θ-α) = 0.8351
cosα/[v₀ cos(θ-α)] = 0.0423

X = 0.8351/(4.9*0.0423²) = 101.46 m

Answer: X = 101.5 m

What is Acid ?

Acid is any material that when dissolved in water has a sour taste, alters the colour of some indicators (blue litmus paper turns red, for example), combines with some metals (like iron) to release hydrogen, reacts with bases to produce salts, and catalyses various chemical reactions. Acids are examples of both organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids. These materials contain one or more hydrogen atoms, which are discharged as positively charged hydrogen ions when they dissolve in a solution (see the Arrhenius hypothesis).

The Brnsted-Lowry theory and the Lewis theory provide broader definitions of an acid that encompass chemicals that display typical acidic behaviour as pure compounds or when dissolved in solvents other than water.

On which factor coefficient of cubical expansion depends?

Answers

I think the question when stated clearly is: What factors does the coefficient of volume expansions depends on? I think that is volume expansion because of the word cubic. In physics, some materials expand in length and in volume, when temperature changes occur. Each kind of material has their empirical values of coefficient of volume expansion in units of m³/°C. So, the obvious factor here is temperature. Generally, as the temperature increases, the volume expands because the molecules move more rapidly occupying more space. For gases, the factor of pressure is also important. But for incompressible objects like solids and liquids, it does not depend on pressure effects anymore.

Which of the following quantities is a vector in character?

electric field
electric charge
electric energy
electric potential difference

Answers

Let us evaluate each of the given answers.
1. Electric field
An electric field is a vector because it has both magnitude and direction. An electric field is defined at a point in space to indicate the Coulomb force that a charged particle will experience, and the direction of the force.

2. Electric charge
The magnitude of the charge on a particle is a Coulomb. Because it is not defined in terms of direction, it is a scalar.

3. Electric energy
Electrical energy defines work done in moving a charged particle. A unit of work has no direction, and it is a scalar.

4. Electric potential difference
An electric potential difference, measured in volts, defines the difference in electric potential energy between charged particles. It is a scalar.

Answer: Electric field is a vector.

The correct option is Option A (Electric Field). Among the given options, the electric field is a vector quantity. The other quantities such as electric charge, electric energy, and electric potential difference are all scalars.

Among the given quantities, the electric field is a vector quantity, while the others are scalars. A vector quantity has both magnitude and direction, making it possible to be represented by arrows indicating the direction and strength of the field.

Key differences :

Electric field: A vector quantity represented by E, which denotes force per unit charge and has both magnitude and direction.Electric charge: A scalar quantity representing the amount of electric charge.Electric energy: A scalar quantity representing the potential energy in the system.Electric potential difference: A scalar quantity representing the difference in electric potential between two points.

For example, the electric potential of a point charge is given by V = kQ/r, which is a scalar, whereas the electric field is defined as the force per unit charge and is a vector.

A model rocket with a mass of 0.181 kg is launched into the air with an initial speed of 92 m/s. How much kinetic energy will the rocket have at a height of 164 m? Assume there is no wind resistance.

303 J - 747 J - 634 J - 444 J

I have tried taking the initial KE with 1/2*.181*92^2 and subtracted the final potential energy .181*9.8*164. This gets me 475, which isn't any of the choices. I picked 444 J since it was the closest, but it was wrong.

Answers

Kinetic energy is the energy that is possessed by an object that is moving or in motion. It is calculated by one-half the product of the mass and the square of the velocity of the object. It is independent of the height for this case. So, we only use the mass of the rocket which is 0.181 kg and the velocity which is equal to 92 m/s. We calculate as follows:
KE = mv^2 / 2KE = 0.181 kg (92 m/s)^2 / 2KE = 765.992 kg-m^2/s^2 or 765.992 J

Therefore, the closest answer to the value we got would be the second option, 747 J.

A heating element being placed in one end of an aquarium can heat the whole aquarium because of heat transfer by convection conduction radiation evaporation

Answers

Answer: Convection

Explanation
(a) It is not conduction
Water is not a good conductor of heat because it has large thermal mass, and it does not sustain large temperature gradients.

(b) It is not radiation
Water undergoes phase changes at 0°C and 100°C. An aquarium does not run at these temperatures. Between these temperatures, the driver for radiative heat transfer between different temperatures in the aquarium will not be significant.

(c) It is not evaporation
Ambient temperature around the aquarium will probably be in the range 20°C o no more than 27°C. The temperature difference between aquarium temperature and ambient temperature will be insignificant, and cannot heat an aquarium.

(d) It is convection
As regions near the heater rise in temperature, convectional flow currents drive warm water toward cold water regions.due to diffusivity. Although it will take some time, the tendency for water in the aquarium is to move toward an equilibrium temperature.

The second option would be nuclear power plants. However, nuclear power plants can leave behind radiation and radiated waste which is considered pollution.

Final answer:

Biomass power plants, geothermal power plants, and nuclear power plants are types of power plants that generate virtually no pollution.

Explanation:

Biomass power plants, geothermal power plants, and nuclear power plants are types of power plants that generate virtually no pollution. Biomass power plants burn organic matter (biomass) from plants to create electricity, while geothermal power plants use the natural heat flow from the Earth's core to generate steam that turns turbines and produces electricity. Nuclear power plants use fission to generate electricity without emitting air pollutants or CO2. However, it is important to note that nuclear power plants produce radioactive waste that needs to be safely stored for an extended period of time.

If the frequencies of two component waves are 24Hz and 20Hz, they should produce beats per second

Answers

When two waves combine, they produce two new waves.

The frequencies of the two new waves are

(the sum of the two original frequencies)
and
(the difference of the two original frequencies) .

The new waves are called the 'beats'.

If the frequencies of the two original waves are 24 Hz and 20 Hz,
then the frequencies of the beats are

(24 + 20) = 44 Hz
and
(24 - 20) = 4 Hz .

These are called the 'beat frequencies'.

Answer:

4 beats per second

Explanation:

When two waves of slightly different frequencies overlap, they produce an interference pattern called beat, which consists in a periodic oscillation whose frequency is called beat frequency.

The beat frequency is equal to the absolute value of the difference between the frequencies of the two original waves:

[tex]f_{beat}=|f_1 -f_2|[/tex]

In this problem, the frequencies of the two waves are:

[tex]f_1 = 24 Hz\\f_2 = 20 Hz[/tex]

So, the beat frequency is

[tex]f_{beat}=|20 Hz-24 Hz|=4 Hz[/tex]

which corresponds to 4 beats per second.

Describe how electromagnetic waves are formed and travel through space.

Answers

In simpler terms, electromagnetic waves are generated by a changing electric or magnetic dipole. When two charges, or magnetic poles, are changing either their position or their strength, the electromagnetic fields around them must change in response. This response can only change at the fastest possible wave speed for electromagnetic radiation: the speed of light.

In general, these waves form from the vibrations of electric and magnetic fields. Unlike mechanical waves, electromagnetic waves do not need a medium to propagate, allowing them to travel through air, solids and vacuum (empty space), which is why they could travel even to outer space. A good example of these are radio waves which travels very fast through space (in light speed which is about 186,000 mi/sec).

Electromagnetic waves are created by a charged particle that generates an electric field. The electric field creates a magnetic field. As the charged particle moves, the electric field and magnetic field keep changing, which causes the wave to move.
