Te question is missing some information. However, I'll try to help you out with the steps.
We have the relation between velocity, wavelength and frequency expressed as follows:
c = λμ
where:
c is the speed of the wave
λ is the wavelength of the wave
μ is the frequency of the wave
Substituting in the above equation, we can get the frequency of the wave which is the number of vibrations per units of time
We can then get the periodic time which is 1/frequency
Hope this helps :)
B will have the greater force
Fc=MV2 /R=Fm
The A particle has less centipetal force and larger radius so larger curve
Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,
So, her kinetic energy right before she hits the water is equal to 2450 J.
