Loudness of sound is determined by its amplitude.

Loudness of sound is determined by its amplitude.The intensity or loudness of a sound depends upon the extent to which the sounding body vibrates, i.e., the amplitude of vibration. A sound is louder as the amplitude of vibration is greater, and the intensity decreases as the distance from the source increases.

The given statement  "Retracting the caliper piston on an integrated parking brake system is different than on a standard caliper" is True because Integrated parking brake systems are becoming more common in newer vehicles.

These systems integrate the parking brake function into the rear calipers, rather than using a separate parking brake assembly. This means that retracting the caliper piston on an integrated parking brake system requires additional steps.

On a standard caliper, retracting the piston is typically done by compressing it with a piston compression tool. However, on an integrated parking brake system, the piston must be rotated while being compressed. This is because the parking brake mechanism is engaged by turning the piston, rather than by pulling a separate parking brake lever.

Overall, retracting the caliper piston on an integrated parking brake system requires extra care and attention to ensure proper functioning of the brake system. It is important to consult the vehicle manufacturer's instructions or a qualified mechanic for guidance on this process.

The motion of an object that is due to only gravity is a falling free fall motion

The values of the motion of the rocks are;

The reason the above values are correct are as follows;

The known parameters are;

The height from which the two students throw the rock, h₀ = 29.4 m

Direction and speed with which one throws the rock, u₁ = 4.9 m/s, downwards

Direction and speed with which the second throws the rock, u₂ = 4.9 m/s, upwards

Required:

(a) The difference in the time each rock spends in the air;

Solution:

The kinematic equation for distance travelled, s, is given as follows;

\(h = h_0 + u\cdot t - \dfrac{1}{2} \cdot g \cdot t^2\)

When the rock reaches the ground, h = 0, we get:

For the rock thrown downwards

\(0 = 29.4 - 4.9\cdot t - \dfrac{1}{2} \times 9.8 \times t^2\)

0 = 29.4 - 4.9·t - 4.9·t²

0 = 4.9×(6 - t - t²) = -4.9×(t² + t - 6)  = -4.9×((t + 3)·(t - 2))

Therefore, t₁ = -3, or 2

Therefore, the time it takes the rock to land is 2 seconds

For the rock thrown upwards

\(0 = 29.4 + 4.9\cdot t - \dfrac{1}{2} \times 9.8 \times t^2\)

0 = 29.4 + 4.9·t - 4.9·t²

0 = 4.9×(6 + t - t²) = -4.9×(t² - t - 6)  = -4.9×((t - 3)·(t + 2))

Therefore, t₂ = 3, or -2

Therefore, the time it takes the rock to land is 3 seconds

The difference in the time the rocks spends in the air, is t₂ - t₁

t₂ - t₁ = 3 - 2 = 1 seconds

The difference in the time the rocks spends in the air, is 1 second

b) To calculate the velocity of each rock as it strikes the ground

Solution:

Taking downward motion as positive, we have;

v = u + g·t

For the rock thrown downwards

v₁ = 4.9 + 9.8×2 = 24.5

The velocity of each rock as it strikes the ground, v₁ = 24.5 m/s

For the rock thrown upwards

v₂ = -4.9 + 9.8×3 = 24.5

The velocity of each rock as it strikes the ground, v₂ = 24.5 m/s

c) The distance between the rocks 0.5 seconds after they are thrown

Solution:

The location of the rock thrown downwards 0.5 second after it is thrown is given as follows;

\(s_{(1, \, 0.5)} = 29.4 - 4.9\times 0.5 - \dfrac{1}{2} \times 9.8 \times 0.5^2 = 25.725\)

The rock thrown downwards is 25.725 m above the ground, 0.5 seconds after it is thrown

The location of the rock thrown upwards 0.5 second after it is thrown is given as follows;

\(s_{(2, \, 0.5)} = 29.4 + 4.9\times 0.5 - \dfrac{1}{2} \times 9.8 \times 0.5^2 = 30.625\)

The rock thrown upwards is 30.625 m above the ground, 0.5 seconds after it is thrown

The distance between the rocks is \(s_{(2, \, 0.5)} - s_{(1, \, 0.5)} =30.625 - 25.725 = 4.9\)

Therefore, the distance between the rocks 0.5 seconds after they are thrown is 4.9 meters

Solids have a distinct volume and form. Although they have a specific capacity, liquids adopt the form of a container. Gases lack a distinct volume or form.

Gas is a sample of matter that adopts the shape of the container in which it is housed and develops a uniform density inside the container.

a)Particle motion

Liquid molecules are more energetic than solid molecules. Further heating will cause the molecules to move so quickly that they won't stick together at all. The gas molecules have the highest energy content.

b)Shapes

Solids are discrete in their shape and volume. Although they take on the shape of the container, liquids have a specific volume. The form and volume of gases are ambiguous.

c)Compressibility

The solid or liquid's constituent atoms, ions, or molecules are in close proximity to one another.

The greater compressible nature of gases compared to liquids or solids is explained by the kinetic-molecular hypothesis.

Answer:

In a solid, atoms vibrate or wiggle, but are locked in place. Solids have a rigid shape, and are hard to compress. In a liquid, atoms have some freedom to move. Liquids take the shape of their container, and are hard to compress. In a gas, atoms move freely. Gases have no definite shape, and are easy to compress.

Explanation:

This is an application of Newton's second law to the forces felt in an elevator.

The use of elevators in public places is a sample of rectilinear motion. If you are accelerating uphill you feel heavier, and if you are accelerating downward you feel lighter. In free fall mode, the elevator's acceleration is the same as the acceleration due to gravity. The enormity of the acceleration due to gravity is 9,8 m/s2,

Since your true weight remains the same, the net force appears because the elevator exerts a smaller normal force on you which is complemented by Newton's Third Law by an equal force downwards on the elevator

So we can conclude that an elevator going up shows constant linear motion, as the elevator will move in a linear line with a constant speed.

The magnitude of the acceleration of the car is 73.077 m/s².

The problem requires to determine the magnitude of the acceleration of a car that is reducing its speed uniformly from 93.0 km/h to 62.0 km/h and also requires to use the number of tire revolutions to calculate it. Let's use the following formula to determine the magnitude of the acceleration of the car:$$v^2 = v_0^2 + 2a\Delta x$$$$\Delta x = \frac{1}{2}(v_0 + v)t$$ Where; v is the final velocity of the car.v0 is the initial velocity of the car.a is the acceleration of the car.Δx is the distance that the car travels.t is the time that the car takes to travel that distance .Here, the initial velocity of the car is v0 = 93.0 km/h and the final velocity of the car is v = 62.0 km/h. Let's convert km/h to m/s. 1 km/h = 0.2778 m/s Initial velocity of the car,$$v_0 = 93.0 \ km/h = 25.83 \ m/s$$Final velocity of the car,$$v = 62.0 \ km/h = 17.22 \ m/s$$The average velocity of the car is given by,$$\bar v = \frac{v_0 + v}{2}$$We need to find time, t .To calculate the time, we use the distance formula for motion with uniform acceleration.$$s = ut + \frac{1}{2}at^2$$Where s is the distance travelled, u is the initial velocity, a is the acceleration, and t is the time taken to travel the distance.Let's write down the values given, and use the formula.$$d = \frac{\pi Dn}{1000} = \Delta x$$$$D = 0.90 \ m$$$$n = 93 \ revolutions$$$$v_0 = 93.0 \ km/h = 25.83 \ m/s$$$$v = 62.0 \ km/h = 17.22 \ m/s$$Distance travelled by the car during 93 revolutions of the tire is given by,$$d = \frac{\pi Dn}{1000}$$$$d = \frac{\pi \times 0.90 \times 93}{1000}$$$$d = 2.5108 \ m$$We can use this distance as $\Delta x$.$$2.5108 = \frac{1}{2}(v_0 + v)t$$$$2.5108 = \frac{1}{2}(25.83 + 17.22)t$$$$2.5108 = 21.525t$$$$t = \frac{2.5108}{21.525}$$$$t = 0.117 \ s$$Using the value of t, we can calculate the acceleration.$$v = v_0 + at$$$$a = \frac{v - v_0}{t}$$$$a = \frac{17.22 - 25.83}{0.117}$$$$a = -73.077 \ m/s^2$$

The magnitude of the acceleration due to gravity on the surface of the moon, in terms of the acceleration due to gravity on the surface of the earth (g), is approximately 0.166g.

The acceleration due to gravity on the surface of a celestial body depends on its mass and radius. In this case, we are comparing the moon to the earth. Given that the moon has a mass roughly 81.3 times less than that of the earth and a radius roughly 3.67 times less than that of the earth, we can determine the magnitude of the acceleration due to gravity on the moon's surface relative to that on the earth's surface.

Using Newton's law of universal gravitation, the formula for the acceleration due to gravity (g) is given by g = GM/r², where G is the gravitational constant, M is the mass of the celestial body, and r is its radius. Since we are comparing the moon to the earth, we can write the equation for the moon's acceleration due to gravity (g_moon) as g_moon = GM_moon/r_moon² and for the earth's acceleration due to gravity (g_earth) as g_earth = GM_earth/r_earth².

Comparing the two equations, we can express the ratio of the acceleration due to gravity on the moon's surface to that on the earth's surface as g_moon/g_earth = (GM_moon/r_moon²)/(GM_earth/r_earth²). Simplifying the equation, we find g_moon/g_earth = (M_moon/M_earth)*(r_earth²/r_moon²).

Given that the mass of the moon (M_moon) is roughly 81.3 times less than that of the earth (M_earth), and the radius of the moon (r_moon) is roughly 3.67 times less than that of the earth (r_earth), we can substitute these values into the equation. Thus, g_moon/g_earth = (1/81.3)*(3.67²) = 0.166.

Therefore, the magnitude of the acceleration due to gravity on the surface of the moon, in terms of the acceleration due to gravity on the surface of the earth (g), is approximately 0.166g.

In this scenario, we compared the acceleration due to gravity on the moon's surface to that on the earth's surface. By utilizing Newton's law of universal gravitation and considering the mass and radius ratios between the moon and the earth, we derived the equation g_moon/g_earth = (M_moon/M_earth)*(r_earth²/r_moon²). Substituting the given values, we found that the magnitude of the acceleration due to gravity on the surface of the moon, in terms of the acceleration due to gravity on the surface of the earth (g), is approximately 0.166g.

This calculation highlights the significant difference in gravitational acceleration between the moon and the earth. The moon's lower mass and smaller radius result in a much weaker gravitational pull compared to the earth. Understanding the factors that influence gravitational acceleration and being able to compare it across different celestial bodies is essential in various fields, including astronomy and space exploration.

To determine the work done on the elevator car, we can use the formula:

Work = Force x Distance x Cos(theta)

where the force is the tension in the cable, and theta is the angle between the direction of the force and the direction of motion (which is zero in this case since the elevator moves vertically).

Since the elevator is lifted at a constant speed, we know that the net force acting on it is zero. Therefore, the tension in the cable must equal the weight of the elevator plus the frictional force:

Tension = Weight + Frictional Force

Tension = (1400 kg)(9.8 m/s^2) + 1275 N

Tension = 13730 N

Using this tension value and the given distance of 36 m, we can calculate the work done on the elevator:

Work = (13730 N)(36 m)(Cos(0))

Work = 494280 J

Therefore, the work done on the elevator car to lift it 36 m is 494,280 J, assuming a constant frictional force of 1275 N.

A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil up and down. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards. In this case, the particles of the medium move perpendicular to the direction that the pulse moves. This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion.

A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right. Energy will begin to be transported through the slinky from left to right.
