Answer:

\large \boxed{\mathrm{B. \ Gravity \ and \ air \ resistance}}

Explanation:

Gravity and air resistance are the forces that get balanced out during a free fall. This is also known as terminal velocity, when gravity = air resistance.

Answer:

B. Gravity and air resistance

Explanation:

Experimentation has proven that :

When the parachute opens, air resistance becomes much greater than gravity. The forces are no longer balanced and this changes the

Analyze why a body undergoing uniform motion eventually comes to rest even in the
djverab [1.8K]

Answer:

It happens due to force of friction

Explanation:

If a body is performing a uniform motion and no external unbalanced force appears to apply on it, then  the body will come to rest after certain time. The reason behind this is the force of friction that is applied in opposite direction of the motion. So, when there is no apparent unbalanced force it means that the only force acting on the body is the force of friction. This force of friction tends to stop the motion after some period of time, because it is acting in the direction opposite to that of motion.

Hence, the reason behind a body undergoing uniform motion eventually stops is <u>Force of Friction.</u>

A car accelerates for 10 seconds. During this time, the angular
bagirrra123 [75]

Answer:

the angular acceleration of the car is 1.5 rad/s²

Explanation:

Given;

initial angular velocity, \omega_i = 10 rad/s

final angular velocity, \omega_f = 25 rad/s

time of motion, t = 10 s

The angular acceleration of the car is calculated as follows;

a_r = \frac{\omega_f - \omega_i }{t} \\\\a_r = \frac{25-10}{10} = 1.5 \ rad/s^2

Therefore, the angular acceleration of the car is 1.5 rad/s²

You hear three beats per second when two sounds tones are generated. The frequency of one tone is known to be 610 Hz. The freque
tiny-mole [99]

The frequency of the other wave is 613 Hz or 607 Hz.

The difference between the frequencies of two waves is called the beat frequency.

Here, one wave has a frequency 610 Hz and the beat frequency is 3 beats per second.

Which has a higher frequency is not mentioned. Therefore, there are two possibilities.

Δf = | 610 - 613 | = 3

or

Δf = | 610 - 607 | = 3

Therefore, the frequency of the other wave is 613 Hz or 607 Hz.
