Answer:
i think it is 40 kilometers in the positive direction... if not im sorry
Explanation:
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.
The diameter of the football player's piston is 0.55 m
Given that the mass of the cheerleader(m) is 55 kg, mass of football player to be hold (M) is 130 kg, height of the players (h) is 1.30 m, radius of the piston corresponding to the diameter (r) is 0.09 m, Diameter of football player's piston (R), P1 is Pressure on the cheerleader's side, P2 is Pressure on the football player's side
Using Pascal's law,
This law states that if there is a change at a point of a body immersed in a fluid then that change will spread thoroughly to each and every point of the body.
The formula of hydraulic system is,
P1= P2
F1/A1 = F2/A2
mg/πr^2 = 4Mg/πR^2
m/r^2=4M/R^2
R^2=4M×r^2/m
By plugging the values, we get.,
R^2=(4×130×0.09^2)/55
R^2=4.21/55=0.076
R=√0.076 = 0.275 m
Hence, diameter of football player's piston is 0.55 m
