According to the question, the speed of the boat in still water is 6 mph.

What is speed?

Speed is a measure of how quickly an object or person moves or travels. It is typically measured in units of distance per unit of time, such as meters per second, miles per hour, or kilometers per hour. Speed can also be expressed as the time it takes to cover a given distance, such as the time it takes to travel one mile or one kilometer.

The speed of the boat in still water can be calculated using the formula V = (D1 + D2) / (T1 + T2), where V is the speed of the boat in still water, D1 is the distance traveled downstream, D2 is the distance traveled upstream, T1 is the time it took to travel downstream, and T2 is the time it took to travel upstream.

In this case, D1 = 6 mph × 3 hours = 18 miles, D2 = 6 mph × 5 hours = 30 miles, T1 = 3 hours, and T2 = 5 hours.

Plugging the values into the formula, we get V = (18 + 30) / (3 + 5) = 48 / 8 = 6 mph.

Therefore, the speed of the boat in still water is 6 mph.

How does acceleration function? What is it?

Any procedure where the velocity varies is referred to as acceleration. There are just two ways to accelerate: changing your speed or changing your direction, or changing both. This is because velocity is both a rate and a direction.

Is acceleration accelerating or constant?

An object is considered to be moving faster or to have an acceleration if its velocity changes. An item can occasionally alter its speed by the same quantity every time or every second.

When a battering ram strikes a wall, it creates a type of mechanical wave known as a pressure wave or a shock wave.

Pressure waves are created by the transfer of energy through a medium, such as a wall or the air, as a result of a sudden change in pressure. The energy from the battering ram creates a compression wave that moves out from the point of impact and spreads throughout the medium. This type of wave is different from transverse waves, such as light or radio waves, which move perpendicular to the direction of the wave's motion, or longitudinal waves, such as sound waves, which move parallel to the direction of the wave's motion. The pressure wave created by the battering ram is an example of a longitudinal wave that moves through the medium, transmitting the energy from the ram to the wall.

Answer:

539 N

Explanation:

The force of gravity (also known as weight) on an object can be calculated using the formula:

F = m * g

where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity.

For a 55 kg person on the surface of the earth, the acceleration due to gravity is approximately 9.8 m/s^2. Therefore, the force of gravity can be calculated as:

F = 55 kg * 9.8 m/s^2 = 539 N

So, the force of gravity on a 55 kg person on the surface of the earth is approximately 539 N.

A toy ball that is advertised to "bounce perfectly elastically" off hard surfaces means that the ball will rebound from a surface with the same energy it had before it hit the surface. In other words, the ball will lose no energy due to inelastic deformation.

Elasticity is a property of materials that refers to their ability to return to their original shape after being deformed by an applied force. When a material is deformed elastically, it experiences a restoring force that is proportional to the magnitude of the deformation.

The elasticity of an object can be determined experimentally by applying a force to the object and measuring the resulting deformation. There are several methods for doing this, depending on the type of object and the conditions under which it is tested.

The height of the cliff from which the stone was dropped is approximately 266.667 meters.

Where h is the height of the cliff, v_0 is the initial velocity (0 m/s), a is the acceleration due to gravity (9.8 m/s^2), and t is the time it took for the stone to fall to the ground.

Since the final velocity of the stone is given (72 m/s), we can use the equation:

v_f^2 = v_0^2 + 2 * a * h

Rearranging the equation and substituting the values of v_f and a:

h = (v_f^2 - v_0^2) / (2 * a)

= (72^2 - 0^2) / (2 * 9.8)

= (5184) / 19.6

= 266.667 m

Velocity is a measure of the rate of change of an object's position with respect to time. The magnitude of velocity is a measure of how fast an object is moving, while its direction indicates the direction of motion.

The unit of velocity is meter per second (m/s), which means the rate at which an object is covering distance in a given direction. The velocity of an object can be calculated using the formula v = Δx/Δt, where Δx is the change in position and Δt is the change in time.

An object can have constant velocity, meaning its speed is the same at all points in time, or its velocity can vary, such as when it is accelerating or decelerating. The velocity of an object can also be negative, indicating that it is moving in the opposite direction.

Answer:

2. they will both hit with the same velocity

Explanation:

The ball which is thrown vertically upwards with a initial velocity V[tex]_{i}[/tex]will have the same velocity as the one thrown downwards with a velocity of V[tex]_{i}[/tex] when it reaches back to the edge of the cliff as no air resistance it acting on it. So the two balls have the same downward velocity at the edge of the cliff. Hence, they hit the ground with the same final velocity.

The frequency of the sound that the driver hears reflected from the wall is approximately 472.56 Hz.

To find the frequency of the sound that the driver of the car hears reflected from the wall, we need to consider the Doppler effect.

The frequency of the sound will change due to the relative velocity of the car and the sound wave.

Let f be the frequency the driver hears reflected from the wall.

Then, we can use the equation:

f = f0 * (v + vs) / (v + vr)

where f0 is the original frequency of the horn,

vs is the speed of sound, and

vr is the relative velocity of the car and the sound wave.

In this case, f0 = 415 Hz, vs = 340 m/s, and vr = 25 m/s (the car is moving toward the wall).

Plugging these values in, we get:

f = 415 * (340 + 25) / (340 - 25)

f = 415 * 365 / 315

f = 472.56 Hz

The required distance between the two charges is r ≈ 0.098 km.

The force of attraction between two point charges is given by Coulomb's law:

F = k * q1 * q2 / r^2

where

F is the force of attraction (in N)

k is the Coulomb constant (8.987551787 x 10^9 Nm^2/C^2)

q1 and q2 are the magnitudes of the charges (in C)

r is the separation between the charges (in meters)

Setting the force equal to the weight (650 N) and solving for r, we get:

650 = k * 1.0 C * 1.0 C / r^2

r = [tex]\sqrt{\frac{k * 1.0 C * 1.0 C}{650N} }[/tex]

Converting r to kilometers:

r = √(k * 1.0 C * 1.0 C / 650 N) / 1000 m/km

r = √(8.987551787 x 10^9 Nm^2/C^2 * 1.0 C * 1.0 C / 650 N) / 1000 m/km

The intensity level of the infrasound 10 km from the source is 62.41 dB.

Low-status sound refers to sound waves having a frequency below the threshold of human audibility, also known as infrasound (generally 20 Hz). Hearing increasingly becomes less sensitive as frequency decreases, hence infrasound needs to have a powerful enough sound pressure for people to be able to hear it. Although many parts of the body may be able to detect infrasound vibrations at higher frequencies, the ear is the primary organ for hearing low-frequency sounds.

There are some uses for the term "infrasonics," which examines sound waves below 20 Hz and up to 0.1 Hz (and rarely to 0.001 Hz). Monitoring earthquakes and volcanoes, as well as mapping underground rock and petroleum deposits, are all done in this frequency range.

The intensity level of a sound decreases with the square of the distance from the source. So, the intensity of the infrasound 10 km from the source will be:

100 dB - 20 log (10 km / 5.5 m)

= 100 dB - 20 log (1818.1818)
