moon?
(a) 12 N (b) 36 N (©) 21 N (d) 63 N​

Answer 1

Answer:

12 N

Explanation:

because the weight on moon is 1/6 of that on the earth

Answer 2

A person with 72 N weight on the earth will weigh 12 N on the moon.

• The gravity of the moon is much less than the gravity of the earth.

• It is approximately one-sixth of the Earth's gravity.

• The weight of a person on the moon can be calculated by the following formula:

$\frac{(Weight on Earth) X (1.622m/s^{2}) }{9.81 m/s^{2} }$

• So the weight of the person on the moon who is weighing 72N on earth will be

= (72 * 1.622) / 9.81

= 11.90

≈ 12 N
