Explanation

The SI unit for flow rate is cubic meters per second (m³/s)

Explanation

Curie (Ci) is a unit that measures the rate of radioactive decay.

1 Curie = 3.7 × 10¹⁰ disintegrations per second.

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

An electron volt (eV) is a unit of energy.

It is defined as the amount of kinetic energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt.

Specifically:

1eV=1.602×10 −19 Joules

Thus, the electron volt is a convenient unit for measuring small amounts of energy, particularly in the fields of atomic and particle physics.
