Answer:
Explanation:
Initial amplitude=
We are given that
Amplitude after 2 s=A=
We have to find the amplitude after 1 s.
We know that amplitude at any time t
Using the formula
When t=1 s

Answer: 80.384 cubic cm /min
Explanation:
Let V denote the volume and r denotes the radius of the spherical snowball .
Given :
We know that the volume of a sphere is given by :-
Differentiating on the both sides w.r.t. t (time) ,w e get
When r= 8 cm
Hence, the volume of the snowball decreasing at the rate of 80.384 cubic cm /min.
