Answer:
L = I α t
Explanation:
given,
rotational inertia = I
initial velocity = ω₀
magnitude of acceleration = α
angular momentum = L
time = t
angular acceleration
ω = α t..............(1)
angular momentum
L = I ω
putting value from equation (1)
L = I α t
Answer:
Given:
Radius of curvature (R) of a spherical mirror = 20
To Find:
Focal length (f)
Explanation:
Formula:
Substituting value of R in the equation:
Answer:
Explanation:
As we know that initial speed of the fall of the stone is ZERO
also the acceleration due to gravity on Mars is g
so we have
now we have
now if the same is dropped for 4t seconds of time
then again we will use above equation
