Explanation:

theres reason boats dont go in shallow water..

All waves move objects from one location to another. The correct option is D.

A wave is a disturbance or variation that moves energy from point to point in a medium and can take the form of an elastic deformation, a variation in pressure, electrical or magnetic intensity, electrical potential, or temperature, or one complete cycle of such a disturbance.

A wave is a disturbance in a medium that carries energy without causing net particle movement.

It could be elastic deformation, a change in pressure, electric or magnetic intensity, electric potential, or temperature. Every wave transports objects from one location to another.

Wind is the most common cause of waves. Wind-driven waves, or surface waves, are created by the friction between wind and surface water.

Thus, the correct option is D.

The frequency of the sound waves reaching the observer's ear is 997 Hz.

The Doppler effect is a physical phenomenon that describes the variation in frequency or wavelength of a wave when the source of the wave is in relative motion with the observer. The Doppler effect applies to light, sound, and other types of waves that transmit through a medium. The frequency of the sound waves heard by an observer is dependent on the speed of the observer and the source of the wave.

The equation used to calculate the apparent frequency of sound heard by a moving observer is: fa = fs (v±vo) / (v±vs)where,fa = the apparent frequency heard by the observerfs = the frequency of the source of the wavevo = the speed of the observer relative to the mediumvs = the speed of the source of the wave relative to the mediumv = the speed of the wave in the medium

Here, The frequency of the roof-mounted siren is 975 Hz.The observer is moving away from the source of the wave at a speed of 6.00 m/s.The speed of the sound wave in the medium is 343 m/s (at 20°C).

The speed of the observer relative to the medium is positive because they are moving away from the source of the wave. Therefore, vo = +6.00 m/s.

The speed of the source of the wave relative to the medium is zero because the siren is mounted on the roof and not moving relative to the medium. Therefore, vs = 0 m/s.

Substituting these values into the equation, we get:fa = fs (v±vo) / (v±vs)fa = 975 Hz * (343 m/s + 6.00 m/s) / (343 m/s + 0 m/s)fa = 997 Hz.

Therefore, the frequency of the sound waves reaching the observer's ear is 997 Hz.

In a car crash, two collisions occur. The impact of the car with the object it hits, and the impact of the occupants with the interior of the car. The aim is always to lengthen these collisions to reduce the forces involved, hence reducing injuries.

During a car crash, there are primarily two collisions that happen. The first collision is the impact of the car with the object. This could be another vehicle, a tree, or a wall. The momentum of the car changes during this time, leading to an abrupt stop or change in direction. The force exerted on the car will be less if this collision time is prolonged, which is why cars are manufactured to crumple upon impact, resulting in a lengthier, less forceful collision.

The second collision occurs between the occupants of the car and the interior of the car. When the car abruptly stops or changes direction, the passengers continue to move at the original speed due to inertia. This might lead to impacts with the dashboard, windscreen, or seat in front. To decrease the force acted upon the bodies of the passengers during this second collision, car safety equipment such as seatbelts and airbags are used. These gadgets increase the collision time, hence reducing the force with which the passengers might collide with the car's interior.

Therefore, the correct response to your question would be the impact of the car with the object.

Kinetic energy = (1/2) (mass) (speed)²

The coaster's original kinetic energy was

KE = (1/2) (2,000 kg) (10 m/s)²

KE = (1,000 kg) (100 m²/s²)

KE = 100,000 kg-m²/s²

old KE = 100,000 joules

After something slowed it down, its new kinetic energy is

KE = (1/2) (2,000 kg) (6 m/s)²

KE = (1,000 kg) (36 m²/s²)

KE =  36,000 kg-m²/s²

new KE = 36,000 joules

The coaster lost (100,000 - 36,000) = 64,000 joules of KE.

Energy is conserved.  It can't evaporate, disappear, or be destroyed.

That 64,000 joules had to go somewhere.

Someone or something had to do 64,000 joules of work on it in order to slow it down.

The work done by the external force on the roller coaster is 64000 J.

Given that the mass of The roller coaster is 2000 kg and its velocity is 10 m/s. The kinetic energy of the roller coaster is given below.

\(KE = \dfrac {1}{2}mv^2\)

\(KE = \dfrac {1}{2}\times 2000\times (10)^2\)

\(KE = 100000 \;\rm J\)

Since the roller coaster has a force of unknown magnitude which decreases its speed to 6 m/s. For this decreased speed, the kinetic energy is given as below.

\(KE'= \dfrac {1}{2}mv'^2\)

\(KE'= \dfrac {1}{2}\times 2000\times 6^2\)

\(KE' = 36000\;\rm J\)

The work done on the roller coaster is calculated by the change in the kinetic energy for both speeds.

Work Done = KE - KE'

Work = 100000 - 36000

Work = 64000 J

Hence we can conclude that the work done by the external force on the roller coaster is 64000 J.

We can use conservation of energy to solve this problem. At the top of the slope, the skier only has potential energy due to their height above the ground. Therefore, the skier's speed at the bottom of the slope is approximately 25.9 m/s.

As the skier skis down the slope, this potential energy is converted to kinetic energy. At the bottom of the slope, all of the potential energy has been converted to kinetic energy, so we can use the conservation of energy equation to find the skier's speed at the bottom of the slope:

PE_top = KE_bottom

mgh = (1/2)mv^2

where m is the skier's mass, g is the acceleration due to gravity, h is the height of the top of the slope above the bottom of the slope, and v is the skier's speed at the bottom of the slope.

We can find h using trigonometry:

h = 78.0 sin(32.0°) = 41.5 m

Substituting in the known values and solving for v:

63.0 kg * 9.81 m/s^2 * 41.5 m = (1/2) * 63.0 kg * v^2 + Fd

where Fd is the force of drag that slows down the skier over the horizontal distance of 105 m. Since we don't know Fd, we'll need to use another equation to solve for it. We can use the following kinematic equation:

v_f^2 = v_i^2 + 2ad

where v_f is the final speed (0 m/s), v_i is the initial speed (v), a is the acceleration due to drag, and d is the distance over which the skier slows down.

Solving for a and substituting in the known values:

0 = v^2 + 2a(105 m)

a = -v^2/210 m

Substituting this value of a into the conservation of energy equation:

63.0 kg * 9.81 m/s^2 * 41.5 m = (1/2) * 63.0 kg * v^2 - (v^2/210 m) * 105 m

Simplifying and solving for v:

v = sqrt(2 * 63.0 kg * 9.81 m/s^2 * 41.5 m / (63.0 kg + 105 m * 9.81 m/s^2 / 210 m)) ≈ 25.9 m/s

When kinetic energy is transferred from a bowling ball to a bowling pin, causing the pin to fly away at a much higher speed than the bowling ball, it indicates that the bowling pin has less mass than the bowling ball.

Kinetic energy is the energy associated with a moving object. When an object is in motion, it has kinetic energy. When work is done on an object, the object's energy changes.

The bowling ball has more mass than the bowling pin. The bowling ball has a greater kinetic energy before it hits the pin than the bowling pin has before it is hit. The bowling ball's kinetic energy is then transferred to the bowling pin, causing it to fly away at a much higher speed than the bowling ball.

In conclusion, this shows that the bowling pin has less mass than the bowling ball and therefore receives the kinetic energy, which results in its speedy movement.

Jane's rate along the summit was 25 mph.

Let's assume that Jane's rate along the summit is represented by the variable "x" in miles per hour. We know that she rode 72 miles uphill at a rate that was 5 mph slower than her rate along the summit. Therefore, her rate uphill would be (x - 5) mph.

To find her average rate for the entire journey, we can calculate the total time taken for each segment and divide it by the total distance covered.

Time taken to ride uphill = Distance / Rate

Time taken to ride uphill = 72 miles / (x - 5) mph

Time taken to ride along the summit = Distance / Rate

Time taken to ride along the summit = 21 miles / x mph

Since the total time taken for the entire journey is 3 hours, we can write the equation:

Time taken to ride uphill + Time taken to ride along the summit = Total time

72 / (x - 5) + 21 / x = 3

By solving this equation, we find that x = 25 mph. Therefore, Jane's rate along the summit was 25 mph.

Answer:

B. The kinetic energy of the ball change into potential energy as the ball rises.

Explanation:

This can seem a little bit confusing at first, but once you understand Kinetic Energy, you'll get it right away. Kinetic Energy is energy an object has when it is moving. So for example, you have kinetic energy when you run, a pen has kinetic energy when you drop it in class, and the ball has kinetic energy as it rises.

However, because of outside forces, objects with kinetic energy will eventually lose it. These forces can be anything from friction as an object slides across a surface, to the negative acceleration due to gravity.

In this question, the force working against the motion of the ball is gravity. As you know, when you throw something up, it has to come down, because of gravity. As the ball goes up, it has enough kinetic energy that it continues its upward motion, however it slowly looses that energy, causing it to slow to a stop before falling back to the ground.

On the way up, the energy of the ball changes from this kinetic (moving energy) to what we call potential energy. Potential energy is exactly what is sounds like, it is the potential for something to begin moving. So, as the ball goes higher, it has a lower chance of continuing to go up (meaning it's loosing it's kinetic energy) and higher chance of falling back down (meaning it's gaining potential energy).

Hope this helps.

The velocity of the ion released from rest and accelerated through a potential difference of 152V is 6.34 × 10^5m/s.

The electric potential difference is a scalar quantity that measures the energy required per unit of electric charge to transfer the charge from one point to another. The electric potential difference between two points in an electric circuit determines the direction and magnitude of the electric current that flows between those two points. A lithium-ion containing three protons and four neutrons has a mass of 1.16 × 10-26 kg. The ion is released from rest and accelerates as it moves through a potential difference of 152 V.

The change in electric potential energy of an object is equal to the product of the charge and the potential difference across two points. The formula to calculate the velocity of the ion released from rest and accelerated through a potential difference of 152V is:

v = √(2qV/m) where q is the charge of the ion, V is the potential difference, and m is the mass of the ion.

Substituting the values in the formula, we get:

v = √(2 × 1.6 × 10-19 C × 152 V/1.16 × 10-26 kg)v = 6.34 × 10^5m/s

Answer:

The pressure value changes 400 % relative to the initial value.

Explanation:

Let suppose that the gas behaves ideally and represents a closed system, that is, a system with no mass interactions so that number of moles is conserved (\(n\)). Since the variables involved in the isothermal process are pressure (\(P\)) and volume (\(V\)). Finally, the process is represented by the following relationship:

\(P_{1}\cdot V_{1} = P_{2}\cdot V_{2}\) (1)

Where:

\(P_{1}, P_{2}\) - Initial and final pressures.

\(V_{1}, V_{2}\) - Initial and final volumes.

If we know that \(P_{1} = P_{o}\), \(V_{1} = V_{o}\) and \(V_{2} = 0.2\cdot V_{o}\), then the final pressure of the closed system is:

\(P_{2} = P_{1}\cdot \left(\frac{V_{1}}{V_{2}} \right)\)

\(P_{2} = 5\cdot P_{o}\)

The pressure value changes 400 % relative to the initial value.

where:

Q = thermal energy [J]

m = mass = 0.5 [kg]

Cp = specific heat = 4,190 [J/kg°C]

T2 = final temperature = 65 [C]

T1 = initial temperature = 30 [C]

Now replacing:

Q = 0.5*4.190*(65 - 30)

Q = 67.04 [J]
