Hydrogen fuel cells is the answer
Lerok [7]3 years ago

Answer: The correct answer is-

hydrogen fuel cells.

Hydrogen fuel cells are used for production of electricity whenever it is required. It is an electrochemical cell that is used to generate electricity when it is supplied with hydrogen and oxygen, which together drain as water and generate electricity.

Renewable energy sources are those that can be replenished or renewed naturally ( such as wind power, solar energy, geothermal energy). In other words, these sources of energy never run off.

Hydrogen fuel can be produced by means of renewable energy sources such as wind or solar energy.

Thus, hydrogen fuel cells do not come under non renewable energy resources.

Consider a series RLC circuit where R = 855 Ω and C = 6.25 μF. However, the inductance L of the inductor is unknown. To find its
sashaice [31]

Answer:

L= 0.059 mH

Explanation:

Given that

R = 855 Ω and C = 6.25 μF

V= 84 V

Frequency

ω = 51900 1/s

We know that

\omega=\sqrt{\dfrac{1}{LC}}

L=Inductance

C=Capacitance

ω =angular Frequency

ω² L C =1

(51900)² x L x 6.25 x 10⁻⁶ = 1

L= 5.99 x 10⁻⁵ H

L= 0.059 mH

A stone is thrown horizontally from the top of a tower at the same instant a ball is droppedvertically. Which object is travelin
Igoryamba

The ball is travelling faster when the two objects hits the level ground below.

<h3>Time of motion of the objects</h3>

The time of motion of the objects depends on height and initial velocity of projection of the objects.

The stone has no initial vertical velocity while the ball has initial vertical velocity.

Thus, the ball is travelling faster when the two objects hits the level ground below.

Net force of 8.0 N acts on an 18 kg body for one minute. Determine the impulse due to the force.
boyakko [2]

Answer:

p = FΔt = 8.0 N(60 s) = 480 N•s

Explanation:

not asked for, but in that time a frictionless 18 kg mass on a horizontal surface will have change velocity by 480/18 = 26.7 m/s.

An impulse results in a change of momentum.
