How much current is flowing through a wire if 21.5 c of charge passes a point in 6.3 seconds?

Explanation:

Current and Charge

The current is a measure of the charge through a conductor over time. If the charge is a function of time it can be computed as

If the charge flow is constant in time, then the current is computed as

Using the values provided in the problem, we have

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
