Answer:
Moment of inertia will be
Explanation:
We have given mass of the person m = 72 kg
Radius r = 0.8 m
Force is given F = 5 N
Angular acceleration
Torque is given by
We know that torque is also given by
, here I is moment of inertia and is angular acceleration
So
The wave length becomes shorter and the pitch becomes higher
Answer:
Light waves
Explanation:
The light in the only wave can travel in the empty space.
Answer:
Explanation:
I don't think it matters while taking a shower, however, while using the restroom, it is especially encourgaed to wipe front to back. The reasoning behind this is to prevent UTI's that are transferred by fecal particles and bacteria from the anus into the vagina. Hope this helps:)
Answer:
E = 16 J
Explanation:
Given that,
Mass of a book, m = 2 kg
Velocity of the book from the backpack, v = 4 m/s
We need to find the kinetic energy of the book falling out of the backpack. Due to the motion of the object, kinetic energy is possessed by it. It can be given by :
So, the kinetic energy of the book is 16 J.
