Answer:
Wavelength
Explanation:
Wavelength is the distance between two corresponding consecutive phases of a waveform. It is usually represented by λ in the mathematical expressions.
A continuous propagating wave repeats its wavelength over the distance.
A wave has crest and trough with respect to time and space.
Wave is defined as a disturbance of any parameter repeated in a cyclic manner over the given time.
To solve this problem we will use the concepts related to power, defined as the amount of energy applied over a period of time.
The energy in this case is the accumulated in the form of potential energy, over a period of time. Thus we will have that the mathematical expression of the power can be expressed as
Here,
E = Energy
t = time
As the energy is equal to the potential Energy we have tat
The weight (mg) of the man is 700N, the height (h) is 8m and the time is 10s, then:
Therefore the correct answer is A.
