The dimensions [M^0 L^1 T^-1] correspond to velocity, which is defined as distance traveled per unit time.

The dimensions [M^2 L^3 T^-1] correspond to volume flow rate, which is volume per unit time.

Density is defined as mass per unit volume, so the unit of density is kg/m³.

To convert m/s to km/s, divide by 1000. Therefore, 3 x 10^8 m/s = 3 x 10^5 km/s.

Energy is defined as work done, which has the dimensional formula [M^1 L^2 T^-2].

Frequency is defined as the number of cycles per unit time, hence its dimensional formula is [T^-1].

Velocity is defined as displacement per unit time, hence its dimensional formula is [M^0 L^1 T^-1].

Coulomb (C) is the SI unit of electric charge.

1 Joule is defined as 1 kg·m²/s² and also equals 1 N·m, hence both are correct.

In the CGS system, the unit of energy is Erg, where 1 Joule = 10^7 Ergs.

Energy is measured in Joules, and 1 Joule is defined as 1 Newton-meter, hence both A and B are correct.

The base unit of temperature in the SI system is Kelvin (K).

1 Joule is defined as the work done when a force of one Newton moves an object one meter, hence 1 J = 1 N·m.

The SI unit of electric charge is Coulomb (C).

The unit of electric charge is Coulomb (C).

The SI unit of work is Joule (J).

Length is a base quantity in the SI system, while force, energy, and pressure are derived quantities.

Meter is a base unit in the SI system, while liter, newton, and joule are derived units.

Acceleration is defined as the change in velocity per unit time, so its dimensional formula is [M^0 L^1 T^-2].

Energy has the dimensional formula [M^1 L^2 T^-2], as it is defined as work done, which is force times distance.

Frequency has the dimensional formula [M^0 L^0 T^-1].

The unit of pressure is Pascal (Pa), which is equivalent to N/m².

Angle is a pure number and has no dimensions, while force, energy, and pressure all have dimensions.

Velocity is a vector quantity as it has both magnitude and direction, while mass, temperature, and speed are scalar quantities.
