Answer: A plz brainliest me
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
Explanation:
Answer:
(a) 
(b) 
(c) 
(d) 
Solution:
As per the question:
Angular velocity, 
Time taken by the wheel to stop, t = 2.4 h = 
Distance from the axis, R = 38 cm = 0.38 m
Now,
(a) To calculate the constant angular velocity, suing Kinematic eqn for rotational motion:

= final angular velocity
= initial angular velocity
= angular acceleration
Now,


Now,
(b) The no. of revolutions is given by:



(c) Tangential component does not depend on instantaneous angular velocity but depends on radius and angular acceleration:

(d) The radial acceleration is given by:

Linear acceleration is given by:
