Light coming through a window!!
Answer:
(a) 
(b) 
Given:
Time period of Pulsar, 
Equatorial radius, R = 15 Km = 15000 m
Spinning time, 
Solution:
(a) To calculate the value of the centripetal acceleration,
on the surface of the equator, the force acting is given by the centripetal force:

(1)
where

(2)
Now, from (1) and (2):



(b) To calculate the tangential acceleration of the object :
The tangential acceleration of the object will remain constant and is given by the equation of motion as:

where
u = 



B because 2800 divide by 40 is 20
Answer:
c). 
Explanation:
As we know that weight of the automobile is given here
so weight = mass times gravity



now from Newton's law
