mass of one liter of water= 1kg
Archimedes says:
F= m g = 1 kg* 9.81 m/s^2 = 9.81 newtons
To calculate the average acceleration of the ball we use the formula,
Here, 
is the final velocity of the ball and 
is the initial velocity of the ball t is the time in contact with the wall.
Given 
towards the wall and 
away from the wall and 
.
Substituting these values in above formula , we get
Here is negative because ball is moving away from the wall.
Therefore, average acceleration of the ball is 
(away from the wall).
The frequency of the other wave is 613 Hz or 607 Hz.
The difference between the frequencies of two waves is called the beat frequency.
Here, one wave has a frequency 610 Hz and the beat frequency is 3 beats per second.
Which has a higher frequency is not mentioned. Therefore, there are two possibilities.
Δf = | 610 - 613 | = 3
or
Δf = | 610 - 607 | = 3
Therefore, the frequency of the other wave is 613 Hz or 607 Hz.

Well you could see it's physical properties have the same descriptions corresponding to a liquid. (Sorry if this doesn't help you..)
