Answer:  C) We always see the same side of the Moon from Earth

Explanation:    

                       The moon is a natural satellite of earth which orbits around the earth with an orbital period (time to complete one revolution ) of around 27 days . Along with this the moon also rotates about its own axis with period of rotation 27 days which is approximately same as the period of revolution . Due to this coincidence that the amount of time the Moon takes to complete one rotation and one revolution are nearly identical , we always see the same side of the Moon from Earth .

           If the Moon did not rotate on itself or did so at a different rate, it would gradually show its entire surface: the visible side and the hidden side. The coincidence between both periods (the rotation and orbital periods) is known as synchronous rotation.

What is the purpose of a tuner in a radio?
Crank

Answer:

A tuner is a subsystem that receives radio frequency (RF) transmissions and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output.

What average net force is required to stop a 1950 kg car in 10.5 s if it’s initially traveling at 28m/s
nika2105 [10]

Answer:

<em>An average net force of 5200 N is needed to stop the car</em>

Explanation:

<u>Cinematics and Dynamics</u>

Cinematics describes the variables involved in the movement without dealing with its causes. There are four main concepts in cinematics: Velocity (or its scalar equivalent, the speed), acceleration, time, and displacement (or the scalar equivalent, distance).

The acceleration can be calculated by:

\displaystyle a=\frac{v_f-v_o}{t}

The initial speed is vo=28 m/s, it stops (vf=0) in t=10.5 seconds, thus the acceleration is:

\displaystyle a=\frac{0-28}{10.5}

a = -2.67~m/s^2

The acceleration is negative because the car loses speed.

Knowing the mass of the car m=1950 Kg, we can calculate the net force required to stop the car by using the formula:

F = m.a =1950*2.67

F = 5200 N

An average net force of 5200 N is needed to stop the car
