What sort of process converts the mechanized energy in the ocean into electricity?

Answers

I think it is the wave energy.
Wave energy also known as the ocean energy is the energy harnessed from the ocean or sea waves. It is a source of power that comes from the endless march of the waves as they roll into the shore then back out. Using wave energy is advantageous as they are environmental friendly as there are no harmful byproducts, and also the energy from waves can be taken directly into electricity-producing machinery and used to power generators.

an electron is held at a distance from a stationary, positively charged object . If the electron is released , what energy change will take place?

Answers

Answer:

Electrostatic potential energy will convert into kinetic energy

Explanation:

When electron is released from rest at some distance from positive charge then due to electrostatic attraction force these two charges will attract each other.

Now in the form of energy we can say that

electrostatic potential energy = $(kq_1q_2)/(r)$

now as the two charges comes closer to each other then the electrostatic potential energy will decrease and hence this energy will convert into kinetic energy of two charges

so we can say

$(kq_1q_2)/(r_2) - (kq_1q_2)/(r_1) = (1)/(2)mv^2$

Electric potential energy will be transformed into kinetic energy.

By connecting two identical storage batteries together in series ("+" to "-" to "+" to "-"), and placing them in a circuit, the combination will yield:a. zero volts.
b. twice the voltage and the same current will flow through each.
c. the same voltage and different current will flow through each.
d. twice the voltage and different currents will flwo through each.

Answers

Answer: option B

Explanation: each cell is suppose to have an emf and an internal resistance.

Let E1 be the emf of the first battery and E2 be the emf of the second battery.

Et is the total emf.

Going by the connection described above, it is a series arrangement.

Hence the total emf is calculated as sum of individual emf

Et = E1 + E2

But each cell are identical, hence E1 = E2 = E

Et = E + E = 2E.

Hence the total voltage is twice the voltage.

Since the connection is a series arrangement, the current passing through each cell is the same.

These points have made option B the correct answer.

Answer:

b) Twice the voltage and the same current

Explanation:

The two batteries are identical, and are connected in series. When elements in a circuit are connected in series, the same current flow through them but the voltage drops are additive.

Since the two batteries are identical, the possess the same voltage of magnitude V.

Therefore, the total voltage, $V_(total) = V + (V)\n$
