The Basketball with the greatest gravitational potential energy is : Basketball 4 feet above the ground ( c )
<u>Given data :</u>
masses = constant
H₁ = 2 ft
H₂ = 3 ft
H₃ = 4 ft
g = 9.81 m/s²
<h3><u>Procedure to determine the basketball with the greatest gravitational P.E </u></h3>
we will apply the equation below
Gravitational potential energy ( U ) = mgh
U = 2 * 9.81 = 19.62
U = 3 * 9.81 = 29.43
U = 4 * 9.81 = 39.24
From the calculations the basketball with the greatest gravitational potential energy is the basketball at 4ft above the ground

The gravitational force experienced by Earth due to the Moon is <u>equal to </u>the gravitational force experienced by the Moon due to Earth.
<u>Explanation</u>:
The force that attracts any two objects/bodies with mass towards each other is defined as gravitational force. Generally the gravitational force is attractive, as it always pulls the masses together and never pushes them apart.
The gravitational force can be calculated effectively using the following formula: F=GMmr^2
where “G” is the gravitational constant.
Though gravity has the ability to pull the masses together, it is the weakest force in the nature.
The mass of the Earth and moon varies, but still the gravitational force felt by the Earth and Moon are alike.
Bulbs c and b would still be screwed in if they were in to begin with and bulbs A, D, and E. would be unscrewed
Answer:
D: 35 m/s
Explanation:
The bus is moving at a speed of 20 m/s.
Thus; v_bus = 20 m/s
Tennis ball thrown horizontally towards the front of the bus is given as 15 m/s.. Thus, v_ball = 15 m/s
No, due to the fact that the bus and the ball are moving at the same time, an observer will think the speed is the sum of that of the ball and the bus.
Thus, it will appear to an observer on the sidewalk that the speed is; v_bus + v_ball = 20 + 15 = 35 m/s
