Answer:
Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320.
Explanation:
The universal law of gravitation states that the force between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
We have to choose the satellite having greatest gravitational force with earth. In all options the distance from the earth is same i.e. 320 km. So, we have to select the satellite having maximum mass because the mass of the earth is constant.
Hence, the correct option is (D) " Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320 ".

Hi , basically the atmosphere is made up of 78% of nitrogen, nitrogen is very special and important because if the air was just made up of oxygen the air that we breath would be very flammable and toxic .That's why we have nitrogen.
The time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds. The correct option is c.
<h3>What is force?</h3>
The force is the action of push or pull to move or stop an object.
Anna pushes a box with a force of 8.00 newtons. she generates a power of 3.00 watts.
Force is related to power by the relation
Force = Power / Velocity
Put the values, we get
8 = 3/V
V = 0.375 m/s
Velocity is defined as the ratio of distance and the time taken.
The box is moved by the distance of 9.72 meters. So, time taken is
V = d/t
0.375 = 9.72/t
t =25.9 seconds.
Thus, time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds.
