Answer
given,
length of rod (L)= 6 m
weight of the rod (W)= 10 N
rotates at = 240 rev/min
=
= 25.13 rad/s
a) Rotational inertia of the rod about axis of rotation
d is the distance from the center of gravity.
d = L/2
I = 27.55 kg.m²
rotational moment of inertia of the rod is equal to I = 27.55 kg.m²
b)angular momentum of rod
L = I ω
L =27.55 x 25.13
L = 692.36 Kg.m²/s
angular momentum of rod is equal to L = 692.36 Kg.m²/s
The all minerals are pure and free from gangue particles......
Answer:
lower pressure, because atoms/molecules need to travel a distance to affect neighboring particles
Burning a substance means that you have damaged it, and this is irreversible, which is a quality that chemical changes have. Burning a substance also changes the substance into ash, which makes it a chemical change as the substance has been formed into something else.
