Answer:
rest and motion are the relative terms because they depend on the observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body
Explanation:
Answer:
Ohm's Law
Explanation:
The relationship: 
where V represents the voltage across a resistor of resistance "R" through which a current (I) flows,
is known as Ohm's Law in honor of Georg Ohm, who discover this proportionality.
The force of gravity (mg) is the force of an object in free fall.
Answer:
µ = 
Explanation:
µ = 1/ sinC
µ -----> refractive index of medium
C ----> critical angle
