A satellite orbits the moon for 3685 s. It has an orbital radius of 2008177 m. then the acceleration of the satellite would be 5.832 m/s²
<h3 /><h3>What is a uniform circular motion?</h3>
It is defined as motion when the object is moving in a circle with a constant speed and its velocity is changing with every moment because of the change of direction but the speed of the object is constant in a uniform circular motion
The acceleration during the uniform circular motion is given by the formula
a = v²/r
where a is the acceleration
v is the velocity of the object
r is the radius of the orbit
As given in the problem a satellite orbits the moon for 3685 s. It has an orbital radius of 2008177 m.
velocity of the satellite
v = 2πr/t
v= (2×3.14×2008177)/3685
v = 3422.34 m/s
acceleration of the satellite
a = v²/r
a = 3422.34²/2008177
a = 5.832 m/s²
Thus, the acceleration of the satellite would be 5.832 m/s²

Work, is the speed at which energy transfers.
Energy, is the capacity to do work.
Power, is the rate at which work is done.
Answer:
12 N/cm²
Explanation:
From the question given above, the following data were obtained:
Weight (W) of block = 240 N
Area (A) = 20 cm²
Pressure (P) =?
Next, we shall determine the force exerted by the block. This can be obtained as follow:
Weight (W) of block = 240 N
Force (F) =.?
Weight and force has the same unit of measurement. Thus, we force applied is equivalent to the weight of the block. Thus,
Force (F) = Weight (W) of block = 240 N
Force (F) = 240 N
Finally, we shall determine the pressure on the floor as follow:
Force (F) = 240 N
Area (A) = 20 cm²
Pressure (P) =?
P = F/A
P = 240 / 20
P = 12 N/cm²
Therefore, the pressure on the floor is 12 N/cm².
