Question

What is the mass of a body which weighs 25 N on the surface of the earth?​

Answer 1

Explanation:

given=.

mg= 25N

m=25/g

m= 25/9.8

Answer 2

Answer:

Earth mass ( M E or M ⊕, where ⊕ is the standard astronomical symbol for planet Earth) is the unit of mass equal to that of Earth. The current best estimate for Earth mass is M ⊕ = 5.9722×1024 kg, with a standard uncertainty of 6×1020 kg (relative uncertainty 10−4).

Explanation:

Divide the object's weight by the acceleration of gravity to find the mass. You'll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you're measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.
