Explanation:
First let's find the electric potential using y = 22.5:
Then, to find the magnitude of the electric field, we just need to divide the electric potential by the distance y:
Answer:
v = 1.2 m/s
Explanation:
The wavelength of the waves is given as the horizontal distance between the crests:
λ = wavelength = 5.5 m
Now, the time period is given as the time taken by boat to move from the highest point again to the highest point. So it will be equal to twice the time taken by the boat to travel from highest to the lowest point:
T = Time Period = 2(2.3 s) = 4.6 s
Now, the speed of the wave is given as:
where,
v= speed of wave = ?
f = frequency of wave =
Therefore,
<u>v = 1.2 m/s</u>
