Answer:

on earth = 833 N

on moon = 136 N

No

Step-by-step explanation:

Weight = mass * gravitational acceleration

(Assume gravitational acceleration on earth = 9.8 ms⁻²)

Weight on Earth = 85 * 9.81

= 833 N

Weight on moon = 85 * 1.61

= 136 N

Weight depends on the gravitational acceleration . But mass is independent from it

Mass doesnt change when we move object to one planet to another planet though Gravitational acceleration is varying planet to planet
