Question

A typical adult human brain has mass of about 1.4 kg. what force does a full moon exert on such a way

Answer 1

Given that the mass of human brain is 1.4 kg, and we need to find out the force exerted by full moon on it.

It can be calculated by the formula:

F= GMm / (r)^square

F= (6.67 * 10^-11 N.m^2 / Kg^2) (1.4 kg) (7.35 * 10^22 kg) / (3.78 * 10^22 m)^2

F= (68.63 * 10^33)/ (14.28 * 10^44) N

F= 4.80 * 10^-11 N

The force exerted in human by the full moon is 2.8 * 10^-11 N
