Explanation:

Answer 2

Only power plants use fossil fuels to transform energy.

What is meant by energy transformation ?

The process of changing one form of energy into another form or the transfer of energy from one location to another is referred to as energy transformation.

Here,

A power plant is a facility that transforms heat energy into electricity. Typically, coal is used by thermal power plants to generate heat.

With the aid of one or more generators that transform various energy sources into electric power, a power plant is an industrial facility used to create electricity.

The water that is kept behind a dam can store electricity in a hydroelectric plant. Potential energy is changed into kinetic energy when water flows from higher altitudes.

Kinetic energy is changed into mechanical energy as the turbine rotates due to the water flow.

Hence,

Only power plants use fossil fuels to transform energy.

The center of your upper spine, your knees, and balls of your feet should line up on top of each other.

Answer:

A golf stance is made up of several elements – the right width of stance, the right amount of knee flex, the angle of the feet and overall posture. We'll look at posture in part 6 of this series. A stance that is too narrow will prevent you from generating a lot of power in your golf swing.

A seesaw remains stationary when two students of equal weight sit on the ends

c

Answer:

the answer is c.

Explanation:

a balanced force is a constant motion, or when the object does not move. because the children have the same weight, they can manage the seesaw to stay still.

As radiation from the sun reaches the earth, the energy is-

A ) Immediately radiated back into space.
B ) Absorbed by only the oceans
C ) Radiated, reflected, and absorbed
D ) Only reflected by clouds in the atmosphere

Answers

Answer:C

Explanation:All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

Answer: A) The amount of heat radiated from the atmosphere to the surface (sometimes called “back radiation”) is equivalent to 100 percent of the incoming solar energy.

B)On its northward journey, the water at the surface absorbs gases like carbon dioxide and chlorofluorocarbons (CFCs) – the latter are, to a large extent, the gases responsible for the ozone hole over Antarctica – as well as excess heat from the atmosphere

C)Water droplets and ice crystals that make up clouds scatter light equally at all wavelengths and therefore appear white. Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo.

D)Clouds cool Earth's surface by reflecting incoming sunlight. ... Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation
