Which kind of energy transformation occurs during skydiving?

First it is gravitational energy, then it changes to Kinetic energy during the fall.

2nd one gravitational to kinetic

"Chemical energy is converted into mechanical energy" is the one kind of energy transformation among the following choices given in the question that occurs in a gasoline-powered car. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer helps you.

I dont really know

Explanation:

The correct answers are kinetic energy and the potential energy.

Explanation:

The kinetic energy is due to the motion of the object. The potential energy is due to the position of the object.

In the given problem, the skater's board falls back to the ramp. When the skater'board falls on the ramp then the potential energy will get decreased and the kinetic energy will get increased and vice versa when the skater's board moves up the ramp.

The total energy of the skater's board remains constant when the skater's board moves down the ramp. The total energy of the skater's board remains constant when the skater's board moves up the ramp. It follows the law of conservation of energy.

Therefore, the correct answers are kinetic energy and the potential energy.

a) potential energy to kinetic energy

b) kinetic energy to mechanical energy

c) mechanical energy to electrical energy

Explanation:

In the hydroelectric power plant, following energy conversions take place -

a)When water falls from great heights , its potential energy is converted to kinetic energy

b)When fast moving water turns the blade of turbine, then its kinetic energy is converted into mechanical energy

c)When the rotating turbine rotate the Electromagnetic coil of generator, the mechanical energy is converted into electrical energy.

A.. Chemical energy is converted into mechanical energy..

Explanation;

In a car engine gasoline is burned, and undergoes a chemical change. Some of the chemical energy stored in the gasoline is converted into thermal energy. This thermal energy is then converted to mechanical energy that moves the car.

-A car engine changes potential chemical energy stored in gasoline into thermal energy and then into kinetic mechanical energy. When gasoline burns it reacts with oxygen to produce carbon dioxide and water vapor. Gasoline is a mixture of octane and similar hydrocarbons.

B) gravitational to kinetic

Explanation:

The skydiver, when he is located at a certain height h above the ground, possesses gravitational potential energy, equal to: where m is the mass of the skydiver, g is the gravitational acceleration and h is the height above the ground. As he falls, its height h decreases, while his speed v increases, so part of the gravitational potential energy is converted into kinetic energy, which is given by so, we see that as v increases, the kinetic energy increases. Therefore the correct answer is

B) gravitational to kinetic

B.) Mechanical to electrical

Water is moving and the turbines turning to electricity

Chemical energy to Mechanical energy.
