Answer:
law of inertial
Explanation:
state that if anobject is in motion it will continue to move until some external force act on it.
Answer:
B: precipitation seeping through pores and cracks in the ground
Explanation:
Man made wells aren't the main source because their isn't enough of them and morning dew doesn't go in to the ground in one main source.
Answer:
a = 2.5 m/s^2
Explanation:
u = 0
v = 25
t = 10
(using first eq. of motion)
a = (v - u) /t
a = (25 - 0) /10
a = 25/10
a = 2.5 m/s^2
Answer:
The moment of inertia of large ring is 2MR².
(A) is correct option.
Explanation:
Given that,
Mass of ring = M
Radius of ring = R
Moment of inertia of a thin ring = MR²
Moment of inertia :
Moment of inertia is the product of the mass of the ring and square of radius of the ring.
We need to calculate the moment of inertia of large ring
Using formula of moment of inertia

Where,
= moment of inertia at center of mass
M = mass of ring
R = radius of ring
Put the value into the formula


Hence, The moment of inertia of large ring is 2MR².
