If a blue whale weighs 200 tons what would it be on the moon?

if no mistaken then it is 300kN

Explanation:

Using SI units (the default if a system is not specified) 200T = 200000kg as the mass of the whale, it would weigh 1960kN in 1g Earth gravity.

On the Moon, the acceleration is 0.166g, to it would weigh about 330kN.

Explanation:

Since the mass of a whale is 200 tons on earth, and the moon has a lighter gravity compared to the earth is about 1/6 as powerful,  the whale would weigh 33.33 tons with the last 3 repeating forever. so about 33 and one third ton on the moon.

This is talking about weight, which is how much it would take to lift this object, but the mass is the the same as mass isn't affected by gravity, only weight is affected by gravity.

Hope this helps!

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
