Answer:
Period, T = 10.86 seconds
Frequency, f = 0.092 Hz
Wavelength,
Speed, v = 3.61 m/s
Explanation:
It is given that,
A woman notices that a wave crest passes by, five more crests pass in a time of 54.0
.
The distance between two successive crests is, the wavelength of wave,
(b)Frequency of a wave is given by number of oscillations per second such that,
f = 0.092 Hz
(a) Let T is the period of the wave. It is inverse of frequency of a wave such that,
T = 10.86 seconds
(c) The distance between two successive crest or trough is called wavelength of a wave, .
(d) The speed of a wave is given by :
v = 3.61 m/s
Hence, this is the required solution.
The power output is 6500 J - ( 12% of 6500 J)
= 5460 J .
Is the first question complete? Because the work done by the river would be equal to work done by the axle of the wheel.
Answer:
The object must be equally buoyant with the surrounding fluid
is an untrue statement - because the object could not float - it could be anywhere in the fluid
Are you asking us what we think of the universe? lol
