Answer: Bases are slippery.

Explanation:

Bases and acids can be determined by the amount of hydrogen or hydroxide ions in each solution. If a solution has more hydrogen ions than hydroxide ions, it is acidic, whereas if it has more hydroxide ions than hydrogen ions, it is basic.

Using a litmus paper test for a acidic/basic solution, the paper will turn different colors. In an acidic solution, paper will turn red, but in a basic solution, paper will turn blue.

Bases, compared to acids, feel slippery on the skin because they interact with fatty acids on the skin. Comparatively, acids feel sticky.

Acids taste sour. Think of an acid like lemon juice, compared to bases, which taste bitter (blood, for example)

Divide the change in velocity by the time interval

For the acceleration of an object, divide the change in velocity by the time interval.

To calculate an object's acceleration, divide the change in velocity by the time period. The right answer is: Divide the velocity change by the time period.

The rate at which an object's velocity varies over time is measured as acceleration. It is computed by dividing the velocity change by the time it takes for that change to occur. The acceleration formula is:

Acceleration = (Change in Velocity) / (Time Interval)

Thus, by determining the change in velocity (the difference between the final velocity and the initial velocity) and dividing it by the time interval, you can find the object's acceleration.

Answer:

The speed of sound, in m/s, through air at this temperature is 343.5 m/s

Explanation:

Given;

distance traveled by sound, d = 1,687.5 meters

time taken for the sound to travel, t = 5 seconds

air temperature, θ = 10°C

Speed of sound = distance traveled by sound / time taken for the sound to travel

Speed of sound = d / t

                           = 1687.5 m / 5 s

                           = 337.5 m/s

Speed of sound at the given temperature is calculated as;

c = 337.5 + 0.6θ

c = 337.5 + 0.6 x 10

c = 337.5 + 6

c = 343.5 m/s

Therefore, the speed of sound, in m/s, through air at this temperature is 343.5 m/s

La dilatación que sufre un balín de acero al pasar de 20 C a 50 C es de 0.00000432 m^3. Esta respuesta se obtiene aplicando la formula de dilatación volumétrica y asumiendo el coeficiente de dilatación volumétrica para el acero es de aproximadamente 0.000036 1/C.

El problema nos pide encontrar la dilatación del acero cuando su temperatura sube de 20 C a 50 C. La dilatación es un fenómeno físico donde los objetos cambian de tamaño debido a los cambios de temperatura. Para entender esto mejor, supongamos que es necesario calcular la dilatación volumétrica de un objeto hecho de acero cuando su temperatura cambia.

La fórmula general para el cálculo de la dilatación volumétrica es: ΔV = β·V0·ΔT, donde ΔV es la dilatación, β es el coeficiente de dilatación volumétrica (acero tiene un valor de aproximadamente 0.000036 1/C), V0 es el volumen inicial ( en este caso 0.004 m3) y ΔT es el cambio de temperatura en grados Celsius (50 C - 20 C = 30 C).

Entonces, sustituimos los valores en la fórmula: ΔV = 0.000036 1/C * 0.004 m3 * 30 C = 0.00000432 m3

Por lo tanto, cuando la temperatura del balín de acero aumenta de 20 C a 50 C, sufre una dilatación de 0.00000432 m3.

Answer:

to mack boats float

Explanation:

without it the boats will sink to the bottom

-- Buoyancy is used to bring crude oil from Saudi Arabi to refineries in the US. The oil is loaded into tanks that are part of supertanker ships. Buoyancy is created by their ship-shape, so they float on water, and they can be dragged across the ocean on top of the water.

-- Buoyancy is used for a cheap thrill on the weekend.  People drive out in the country and find a place where they can buy a ride under a hot-air balloon.  The balloon is filled with hot air from a propane burner under its opening, and then it rises up off the ground because of its buoyancy in cool air.

-- Buoyancy is used cleverly by factories, to get rid of their gaseous and particulate wastes.  The wastes are heated, and then blown into tall "smokestacks" connected to the factory.  Then they rise because of the buoyancy created by hot stuff in cool air.  When they leave the top of the smokestack, they keep rising for a while.  Then, weather systems blow them away from the factory, over into other people's neighborhoods, where they finally sink to the ground in places where nobody knows where they came from.

-- Buoyancy is used in teapots, coffee makers, and lava lamps.  A heat source is placed under the bottom of the container. Heat is conducted through the bottom of the container, and it heats the fluid that's in contact with the inside of the container on the bottom. The hot fluid rises to the top of the container, because of the buoyancy created by hot stuff surrounded by cool stuff.  At the same time, cool stuff flows in to take its place at the bottom.  

In pots and pans and tanks where buoyancy is used this way, the motion of the fluids up and down and around is called "convection".

Answer:

5.11 kg

Explanation:

Hooke's law states that stress is directly proportional to strain. It can be represented by the equation:

F = -kx

Where x is the displacement of the spring’s end from its equilibrium position, F is the force applied to the spring, k is a constant known as spring constant.

At first a force (F) of 62 N i used to stretch a spring by 12 cm (x).

Substituting into Hooke's equation:

F = kx

k = F/x = 62 / 12 = 5.17 N/cm

The spring is then held vertically and an object. The object is acted by upon by acceleration due to gravity since it is vertically upward. Therefore the force created by the object F = mg where g = acceleration due to gravity = 9.8 m/s². It causes a stretch (x) of 9.7 cm

Therefore:

mg =  5.17 N/cm × 9.7 cm

9.81m = 50.117

m = 50.117 / 9.81 = 5.11 kg

The change in electrical potential energy of the system can be calculated using the equation: ΔPE = q * ΔV, where ΔPE is the change in potential energy, q is the charge, and ΔV is the change in electric potential. In this case, the change in electrical potential energy of the system is 0.060 J.

The change in electrical potential energy of the system can be calculated using the equation:

ΔPE = q * ΔV

Where ΔPE is the change in potential energy, q is the charge, and ΔV is the change in electric potential.

In this case, the charge q is 12 μC and the change in electric potential is given by ΔV = E * d, where E is the electric field strength and d is the displacement.

Plugging in the values, we get:

ΔPE = (12 μC) * (250 N/C) * (20.0 cm) * (1 m/100 cm)

Simplifying the units and the calculation, the change in electrical potential energy of the system is 0.060 J.

To find the change in electrical potential energy, calculate the work done by the electric field as the charge moves along the x-axis. The work done equals 6 × 10⁻⁴ J, which is the change in electrical potential energy.

Change in Electrical Potential Energy

To determine the change in electrical potential energy of the system, we need to consider the direction and magnitude of the electric field and the charge's movement.

The electric field extbf(E) is directed along the positive x-axis with a magnitude of 250 N/C. The charge q is 12 μC (microcoulombs), or 12 × 10-6 C.

The initial position of the charge is at the origin (0,0), and the final position is (20.0 cm, 50.0 cm). Convert these to meters: (0.2 m, 0.5 m). The electric field works only along the x-axis, so we only need the change in the x-coordinate.

Work done by the electric field is defined as:

W = qEΔx

Here, Δx = xfinal - xinitial = 0.2 m - 0 m = 0.2 m.

Now, substitute the values:

W = (12 × 10⁻⁶ C) * (250 N/C) * (0.2 m)

W = 12 × 10⁻⁶ * 250 * 0.2

W = 12 × 10⁻⁶ * 50

W = 600 × 10⁻⁶ J

W = 6 × 10⁻⁴ J

This work is equal to the change in electrical potential energy (old{ΔU}) of the system.

The change in electrical potential energy of the system is 6 × 10⁻⁴ Joules.

Final answer:

The force that knocks an object moving forward sideways is an external force, as described by Newton's first law of motion. This could be due to a collision, friction, or other forces changing the object's direction, like the effect felt during a sharp turn in a car.

Explanation:

The force you are asking about, when an object moving forward gets knocked sideways, is typically called an external force. In accordance with Newton's first law of motion, which states that an object will maintain its state of motion unless acted upon by a net external force, this sideways force changes the object's state of motion. In real-world situations, several forces can act as this external force, such as friction, tension, normal force, or even another object colliding with the one in motion.

For example, if an object like a rolling ball is knocked sideways by another ball, the sideways force is the result of the collision between the two balls. This changes the direction of the ball's momentum, creating a new motion path. Similarly, when a car makes a sharp turn, the force exerted by the friction between the tires and the road surface is what changes the direction of the car's velocity. This is why you might feel a force pushing you sideways in the seat, often referred to as a centrifugal effect, which is in fact the inertia of your body wanting to continue in a straight line.

The image distance is 17.56 cm

Explanation:

We have,

Height of light bulb is 3 cm.

The light bulb is placed at a distance of 50 cm. It means object distance is, u =-50 cm

Focal length of the lens, f = +13 cm

Let v is distance between image and the lens. Using lens formula :

[tex]\dfrac{1}{f}=\dfrac{1}{v}-\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{f}+\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{13}+\dfrac{1}{(-50)}\\\\v=17.56\ cm[/tex]

So, the image distance is 17.56 cm.

Final answer:

Explanation on how to calculate the image distance for a light bulb placed 50 cm away from a thin convex lens with a 13 cm focal length.

Explanation:

The image distance for the light bulb placed 50 cm away from a thin convex lens with a focal length of 13 cm can be calculated using the lens formula:

1/f = 1/do + 1/di

Where:

f = focal length of the lens (13 cm)

do = object distance from the lens (50 cm)

Solving for di, the image distance would be around 15.62 cm.

Answer:

a. 0.882 N b. 9.8 m/s² c. 6.42 m/s

Explanation:

a. The net force acting on the ball is its weight W = mg were m = mass of ball = 90 g = 0.090 kg and g = acceleration due to gravity = 9.8 m/s²

W = mg = 0.090 kg × 9.8 m/s² = 0.882 N

b. The acceleration = g = acceleration due to gravity = 9.8 m/s² since it is falling freely

c. Using v² = u² + 2as where v = final velocity of ball, u = initial velocity of ball = 0 m/s, a = acceleration of ball = 9.8 m/s² and s = height = 2.1 m. Substituting the values of the variables, we ave

v² = u² + 2as = 0² + 2(9.8 m/s²) × 2.1 m = 41.16

v = √41.16 = 6.42 m/s

Answer:

Explanation:

Displacement is the shortest distance possible between initial and final position.

As the athlete is in circular motion , displacement is zero. [ THis is because , the initial and final position is the same ]

Distance covered in 1 round = Circumference of the circle

Circumference of the circle = 2πr

Diameter = 200 m

Radius = 100 m

Distance covered in 1 round[ 40 sec ] = 2 × 22/7 × 100 = 628.57 m

Distance covered in 1 sec = 628.57 ÷ 40 = 15.71 m

2min 20 sec = 140 sec

Distance covered in 140 sec = 15.71 × 140 = 2199.4 m

For each complete round the displacement is zero. Therefore for 3 complete rounds, the displacement will be zero.

At the end of his motion, the athlete will be in the diametrically opposite position. That is, displacement = diameter = 200 m.

Hence, the distance covered is 2200 m and the displacement is 200 m.

Given that,

Kinetic energy of an automobile is 2300J

K.E = 2300J

The formula for kinetic energy is

K.E = ½mv²

So, if the speed of the automobile is increased by 6, what is the kinetic energy

Now v' = 6v.

The mass of the automobile is constant.

Therefore, the kinetic energy is

K.E' = ½mv'²

Where v' = 6v

K.E' = ½m(6v)²

K.E' = ½m × 36v²

K.E' = 36 × ½mv²

Where, from above ½mv² = 2300J

Then,

K.E' = 36 × 2300 = 82,800J

The kinetic energy of the automobile when it increase it's speed is 82,800J

When the automobile moves with six times the initial speed, its kinetic energy will be 82800 J.

The kinetic energy (KE) of an automobile is given by the formula:

[tex]\[ KE = \frac{1}{2}mv^2 \][/tex]

where[tex]\( m \)[/tex]is the mass of the automobile and [tex]\( v \)[/tex] is its velocity.

If the automobile's kinetic energy is 2300 J at a certain speed, then we can denote this initial kinetic energy as [tex]\( KE_{initial} \)[/tex]and the initial speed as[tex]\( v_{initial} \)[/tex]. We have:

[tex]\[ KE_{initial} = \frac{1}{2}mv_{initial}^2 = 2300 \, \text{J} \][/tex]

When the automobile moves with six times the initial speed, its new speed is [tex]\( v_{new} = 6v_{initial} \).[/tex] The new kinetic energy[tex]\( KE_{new} \)[/tex]can be calculated using the same formula:

[tex]\[ KE_{new} = \frac{1}{2}m(6v_{initial})^2 \] \[ KE_{new} = \frac{1}{2}m \cdot 36v_{initial}^2 \] \[ KE_{new} = 36 \cdot \frac{1}{2}mv_{initial}^2 \] \[ KE_{new} = 36 \cdot KE_{initial} \][/tex]

Since [tex]\( KE_{initial} = 2300 \, \text{J} \)[/tex], we substitute this value into the equation:

[tex]\[ KE_{new} = 36 \cdot 2300 \, \text{J} \] \[ KE_{new} = 82800 \, \text{J} \][/tex]

The answer is: 82800.
