Answer:
Explanation:
The momentum of inertia of the solid sphere is :
m is the mass of solid sphere
r is the radius of sphere
Since, 
........................(1)
Let r' is the radius of second sphere such that, r' = 2r. New moment of inertia is given by :
Similarly,
.
........................(2)
Dividing equation (1) and (2) as :
So, the ratio of their moments off inertia is 32:1
World shall know pain im not helping figure it out urself + RATIO
Answer:
Explanation:
The experimenter is rotating on his stool with angular velocity ω ( suppose )
His moment of inertia is I say
We are applying no torque from outside . therefore , the angular momentum will remain the same
Thus angular momentum L = I ω = constant
Thus we can say I₁ ω₁ = I₂ω₂ = constant
here I₁ is the initial moment of inertia and ω₁ is the initial angular velocity
Similarly I₂ is the final moment of inertia and ω₂ is the final angular velocity
When a been bag is dropped on his lap , his moment of inertia increases due to increase in mass
In the above equation, when moment of inertia increases , the angular velocity decreases . So its motion of rotation will decrease .
Answer:
Air molecules and suspended water droplets collide as they swirl around in the clouds. Warmer air and water droplets rise, carrying charges with them. The result is an excess of positive charge near the cloud tops, and an excess of negative charge in the bottom layers of the clouds.
they are knocked off some ice and added to other ice as they crash past each other
Explanation:
Answer:
a)
b)Does not affect the long term.
Explanation:
Given that
A = A0 cos(ωt)
This is linear equation so integration factor ,I
Now by using linear equation property
b)
at t= 0
So the initial condition does not affect the long term.
