Answer:
Current flowing in the cell will be equal to 0.1284 mA
Explanation:
We have given charge q = 3.70 C
And time through which charge is flowing = 8 hour
We know that 1 hour = 60 minutes, and 1 minute = 60 sec
So 1 hour = 60×60 = 3600 sec
So 8 hour = 8×3600 = 28800 sec
We know that current is rate time rate of flow of charge
So current
So current flowing in the cell will be equal to 0.1284 mA

Explanation:
<u>Simple Harmonic Motion</u>
A mass-spring system is a common example of a simple harmonic motion device since it keeps oscillating when the spring is stretched back and forth.
If a mass m is attached to a spring of constant k and they are set to oscillate, the angular frequency of the motion is
The equation for the motion of the object is written as a sinusoid:
Where A is the amplitude.
The instantaneous speed is computed as the derivative of the distance
And the maximum speed is
Solving for the amplitude

Answer:
A. Another form of energy is nuclear energy. ... The guitar produces sound energy when the guitarist plucks the strings.
B. The organ that we use to sense sound energy is the ear. ... Together, they gather sound waves, amplify the waves, and change their kinetic energy to electrical signals. The electrical signals travel to the brain, which interprets them as the sounds we hear.
