How can solar energy be used to produce electricity
Neko [114]

Answer:

Explanation:

Electricity is generated from solar energy predominantly by the use of photovoltaic cells.

The sun is the ultimate source of energy for all life and the bulk of the solar system at large.

Energy from the sun is used for various life processes and other abiotic uses.

In order to harness the sun's energy to produce electricity, a photovoltaic cell is required. These cells are often used in making solar panels which are available in most places today.

Electricity is produced by the movement of electrons within a cell or a body. In a photovolatic cell, the radiation from the sun causes chemical reactions to occur on the surface of these materials. The reaction is such in which electrons are produced. The movement of electrons in these cells results in the generation of electricity.

In some other cases, sunlight can be concentrated for heating water to produce steam. Steam can be used to drive turbines to produce electricity too.

5. A ball is sitting at rest on the floor. What will happen if a balanced force is applied to the ball? *
Leno4ka [110]

When the balanced force is applied on the ball It will roll away from the force.

Ford used to make a 7.0 liter engine. Calculate how many many cubic inches would be the same size engine.
Anestetic [448]

Answer : The volume of engine in cubic inches is, 427.166\text{ inch}^3

Explanation :

As we are given that the volume of engine is, 7.0 liters. Now we have to calculate the volume of engine in cubic inches.

Conversion used :

1\text{ liter}=1000cm^3

So, 7\text{ liter}=7000cm^3

1\text{ inch}=2.54cm

or,

1cm=\frac{1}{2.54}\text{ inch}

1cm^3=(\frac{1}{2.54}\text{ inch})^3

As,

1cm^3=(\frac{1}{2.54}\text{ inch})^3

So,

7000cm^3=\frac{7000cm^3}{1cm^3}\times (\frac{1}{2.54}\text{ inch})^3=427.166\text{ inch}^3

Thu, the volume of engine in cubic inches is, 427.166\text{ inch}^3
