Una ola en el océano tiene una longitud de 15m. Una onda pasa por unadeterminada positionfija cada 3s. ¿Cuál es la velocidad de la onda?

Speed, v = 5 m/s

Explanation:

A wave in the ocean has a length of 15m. A wave passes through a fixed position every 3s. What is the speed of the wave?

It is given that,

Length of a ocean wave is 15 m

Time period of the wave is 3 s

We know that, frequency = 1/time period

Let v is the speed of the wave. So,

So, the speed of the wave is 5 m/s.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
