Question

A calibrated spring balance may be used anywhere in the universe to correctly measure

Answer 1

Force and Weight  

Explanation:

• A spring balance which has been calibrated to measure force in newtons will measure force or weight anywhere, and is independent of any variations within the force of gravity provided that the effect of gravity on the spring itself are often regarded as. negligible.

• Spring balance is a mechanical device used for measuring the weight or force of an object by opposing the force of gravity with the force of an extended spring.  

• The principle behind its working is the principle of Hooke's law .
