Heat absorbed to raise the temperature is given by

here
m = mass
c = 7.11 J/g C

Q = 138 KJ
Now by using the above formula we will have



So the amount of the substance will be 3.88 kg
shm
displacement is A*sin 2pi f t
vel =( A*2*pi*f*)*cos 2 pi f t
accn =-( A*2*pi*f*)^2*sin 2 pi f t
accn = (0.01*2*3*5)
accn = (0.01x30)^2=9
Explanation:
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.
