Nadya [2.5K]

Emit greenhouse gases

Explanation:

Nuclear power is regarded as a clean energy source because it doesn't produce or emit greenhouse gases.

Greenhouse gases are mostly generated by the use of fossil fuels that pollutes the environment causing surging global temperature.

Nuclear power is produced by the splitting of radioactive minerals in rods. The process releases a large amount of energy. When the fuel elapses, only radioactive wastes remains.

There is no production of any greenhouse gas in the process of harnessing nuclear energy.

This is why it is considered a clean energy source.

A bar magnet has five lines of force cutting one square centimeter (1 cm2). Assuming that each line of force represents 30 Wb of
user100 [1]

Answer:

The magnetic flux density is 3 x 10⁵ Wb/m²

Explanation:

Given;

magnetic flux of each line of force, Ф = 30 Wb

area of the bar magnet, A = 1 cm² = 1 x 10⁻⁴ m²

The flux density of the magnet is the measure of the concentration of the magnetic flux per unit area. The unit is Wb/m² or Tesla.

B = Ф / A

B = 30 / (1 x 10⁻⁴ )

B = 3 x 10⁵ Wb/m²

Therefore, the magnetic flux density is 3 x 10⁵ Wb/m²
