Answer:
I think they are called balanced forces
Explanation:
Answer:

Explanation:
We have given initial length of the steel guitar l = 1 m
Cross sectional area 
Young's modulus 
Force F = 1500 N
So stress 
We know that young's modulus 
So 

Now strain 


True. Since Inertia states this law, we are bound to believe greater mass = greater resistance in change of motion
Replaces spring 2. the mass of the weight and pulley are unchanged: m=5.8 kg and mp=1.7 kg
