Answer
given,
expression of Kinetic energy of rotating body
ω = 34.0 rad/s
Assuming mass of the particle equal to 13 Kg
and perpendicular distance from the particle to the axis is r = 1.25 m
now,
moment of inertia of particle = ?
from the given expression
..............(1)
we know
v = r ω
putting value in equation (1)
I = 20.3125 kg.m²
Answer:
Stephen William Hawking
Explanation:
Stephen William Hawking was a popular theoretical physicist born on 8th January 1942.
He served as the professor of mathematics at the Cambridge university
He was director at the center for theoretical cosmology.
He has theorized that the black holes will emit radiations and the radiations is known by his name Hawking's radiation.
His book 'The Brief History of Time' appeared as one of the best seller according to the Sunday Times.
Hawking's was diagnosed for a rare disease named as motor neuron disease.
He received numerous awards and elected as the fellow of royal society.
He passed away on 14th March 2018.
Answer:
0m/s²
Explanation:
The acceleration of the given body whose motion has been described will be zero.
This is because the body moves with a constant velocity.
Acceleration is defined as the rate of change of velocity with time.
Since in this problem, the velocity is not changing per time, then the acceleration would be zero.
A body moving steadily implies that such body is not changing its motion by the virtue of its velocity and even direction.
