Explanation

The unit of magnetic flux density is Wb m⁻² (weber per square meter).

It is commonly referred to as a tesla (T), which quantifies the strength of the magnetic field.

Explanation

Concave lenses are also known as diverging lenses, as they spread out light rays and diverge them away from a single point.

Explanation

• A rivet is used to fasten two hard materials together.
• Such as metal plates or sheets.

Explanation

Explanation

• Aluminum is a non-ferrous metal.
• It is not capable of being magnetized or attracting magnets.

Explanation

Explanation

Using the Parallel Axis Theorem:

I = I_CM + Md^2

where I_CM = MR^2/2 and d = R (radius)

I = MR^2/2 + MR^2

= 3/2 MR^2

Explanation

The speed of sound in an ideal gas is primarily dependent on the temperature of the gas and its molecular weight.

While the density of the gas does influence the speed of sound, it changes with temperature and pressure.

Explanation

The storage battery provides electrical energy through chemical reactions.

These reactions occur between the materials inside the battery.

It converting chemical energy into electrical energy.

Explanation

The wavelength of the radiation emitted when an electron in a hydrogen atom jumps from a higher orbit (n = 2) to a lower orbit (n = 1) can be calculated using the Rydberg formula:
