To solve this problem we will apply the concept given by the law of gravitational attraction, which properly defines gravity under the function

Here,
G = Gravitational Universal Constant
M = Mass of Earth
r = Distance between the human and the center of mass of the Earth
The acceleration due to gravity when is 4 times the mass of Earth and 3 times the radius would be given as,




The weight is defined as

So the new weight would be given as






Therefore the weight under this condition is 288.8N
Answer:This Answer is B
Explanation:
Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
A field force is a force that acts equally on all the items in it. For example, the force you exert on the chair when you push it acts only on the chair - not on the table, other chairs, etc. around it.
Whereas a force like gravity acts equally on everything - on the apple, on the leaves, on the other apples in the tree, etc.
