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

She must find her more like herself than you i guess.
Answer:
The first case requires more force to spin de bucket.
Explanation:
As we know, the centripetal force is directly proportional to the mass, the equation is given by:

The first case has a quarter more water than the second case, therefore the first case requires more force to spin de bucket.
