Element formula....
I do hope this helps you Darling
Given that :
Power (P) = 30 W ,
time (t) = 40 s,
Work = ?
we know that, power is defined as rate of doing work
Power = Work ÷ time
=> Work = Power × time
= 30 × 40
<em> W = 1200 J</em>
That's a true statement ... not a question.
When the kinetic energy of an object changes, energy
may be transferred either to or from the object.
Answer:
Amplitude, A = 5 m
Explanation:
Let a progressive wave is given by equation :
.....(1)
The general equation of a progressive wave is given by :
....(2)
Here,
A is the amplitude of the wave
is the angular frequency
k is propagation constant
We need to find the amplitude of the wave.
If we compare equations (1) and (2), we find that the amplitude of the given plane progressive wave is 5 m.
