Equal to the angle of reflection.
Vf = Vi + at
Vf = 0 + 5.4•28
= 151.2m/s..
not sure if its right
The given question is incomplete. The complete question is:
Estimate the volume of each ball. Use the formula 
where v is the volume and r is the radius. record the volume in table A of your student guide. The radius of the tennis ball is 2.1 cm and the radius of thr golf ball is 2.0 cm. What is the estimated volume of the table tennis ball in 
What is the estimated volume of the golf ball in
Answer: Volume of the tennis ball is 
and Volume of the golf ball is 
Explanation:
We have to find the Volume of tennis ball and golf ball by using the formula
Radius of the tennis ball = 2.1 cm
Radius of the golf ball =2.0 cm.
Putting the value of radius in the formula , we get:
Volume of the tennis ball = 
Volume of the golf ball = 
Volume of the tennis ball is and Volume of the golf ball is

Wavelength decreases
Explanation:
When the frequency of a wave increases from 200hz to 300hz, the wavelength of the whale noise will decrease.
- Frequency is the amount of wave that passes through a point at a particular time. The higher the frequency, the more the number of wave passing a particular point.
- The wavelength of a wave is the distance between two successive crest or trough in a wave. The longer the wavelength, the more the separation between a wave crest.
- A wave is a disturbance that consistently transmits energy.
When the number of wave passing through a point increases, the wavelength is reducing.
Wavelength and frequency are inversely related.
