Answer:
Force to stretch the wire is 250 N
Explanation:
As we know that modulus of elasticity will remain the same for the wire if the applied stretch to the wire is within elastic limit
So we will have
now we have
so we can write it as
False because friction will generate heat energy and/or sound energy etc. Think of a car stopping or a broom sweeping the ground.
If a constant force is applied on a body, the body moves with constant acceleration.
Answer:
we have τ = I * α as the rotational equation of motion
and we also have τ = F * r
so the torque τ = 5* 0.16 Nm = 0.8 Nm
from your plot of θ vs T^2 , calculate the slope of the line
this slope will be angular acceleration α.
Then you get I = τ/α
