C will his weight be more less or the same ​

Answer 1

Answer:

A) his weight on the Earth is 80 kg

B) When he arrives on the moon his weight will be less.

C) His weight would be less.

Explanation:

His weight will be less in the moon because of it's less gravitational force (moon).

Answer 2

Answer:

Astronaut having a mass of 80 kg.

The Mass of Astronaut will always be the same no matter where he goes. But what shall change is his weight.

Weight on earth = mg

= 80*9.8 N

= 784 N

Weight on moon = mg

The acceleration due to gravity on moon is 1.6 m/s^2.

80*1.6 N

= 126 N

Thus, on earth the astronaut will feel heavier than on moon.

I hope that helps.
