Respuesta :
The period of wave that moves a boat upside down 10 times in 2 seconds is 5 second.
What is the period of wave?
The period of a wave is given as the number of times a wave complete its turn in a second. The wave period can be given as:
Period of wave = Oscillation per second
The number of oscillations of the wave are equivalent to the oscillation of the boat.
The number of oscillation in 2 second are 10. Thus, the period of wave is given as:
2 sec = 10 oscillations
1 sec = 10/2 oscillations
1 sec = 5 oscillations
Thus, the number of oscillations per second are 5. Therefore, the period of wave is 5 second.
