Answer:
Explanation:
Given
Mass of solid uniform disk
radius of disk
mass of lump
distance of lump from axis
Moment of inertia is the distribution of mass from the axis of rotation
Initial moment of inertia of disk
Final moment of inertia =Moment of inertia of disk+moment of inertia of lump about axis
Answer:
E = 0.1472 J
Explanation:
Given that,
The number of turns in the solenoid, N = 2100
Area of the solenoid, A = 10 cm² = 0.001 m²
The length of the solenoid, l = 30 cm = 0.3 m
Current in the solenoid, I = 4 A
We need to find the magnetic energy stored in the solenoid. The expression for the stored energy is :
Where
L is self inductance of the solenoid,
So,
So, 0.1472 J of energy is stored in the solenoid.
Answer:
Explanation:
Given
mass of disk
diameter of disc
Force applied
Now this force will Produce a torque of magnitude
And Torque is given Product of moment of inertia and angular acceleration
Moment of inertia for Disc
