In solids: All metals are good conductors of electricity as they contain free moving electrons. Non-metals doesn't conduct , but we consider Graphite the only non-metal that can conduct electricity for the presence of free moving electrons.
In Liquids ; Ionic compunds contains free moving ions , so they conduct electricity as well .
The value of spring constant and the oscillator's damping constant is
K= 6605.667008, b= 0.002884387
Explanation:
For Weakly damping spring oscillator
K/m = W_0^2 (at resonance)
K= mW_0^2
=0.206 * ( 2π * 28.5) ^2
=0.206 * (2π)^2 * (28.5)^2
K= 6605.667008
F = - bV
b= -F/V = -F/ -W_0 * m
=F/W_0 * m
= 0.438N / 2π * 28.5 * 0.848
b= 0.002884387
Answer:
m/s/s
Explanation:
Acceleration is change in velocity over time.
a = Δv / t
a = [m/s] / [s]
a = [m/s/s]
Answer:
The magnitude of change in momentum of the ball is 
and impulse is also
Explanation:
Given:
Velocity of a pitched ball 
Velocity of ball after impact 
From the formula of change in momentum,
Here mass is not given in question,
Mass of ball is 
Change in momentum is given by,
Magnitude of change in momentum is
And impulse is given by
So impulse and
Therefore, the magnitude of change in momentum of the ball is and impulse is also 
Answer:
NO
Explanation:
I=mr^2 this means moment inertia depends upon mass and square of radius or distance.
