Angle is a dimensionless quantity and has the dimension [M^0 L^0 T^0].

Time has the dimension [M^0 L^0 T^1].

Velocity has the dimension [M^0 L^1 T^-1], as it is defined as distance per unit time.

Energy has the dimension [M^1 L^2 T^-2].

Temperature is a scalar quantity as it has magnitude but no direction, while velocity, force, and acceleration are vector quantities.

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

In a closed system, angular momentum is conserved, while linear momentum and kinetic energy may not be.

In a closed system with no external torques, angular momentum is conserved.

In a closed system with no external torques, angular momentum is conserved.

In an isolated system with no external torques, angular momentum is conserved.

In an isolated system, energy, momentum, and mass are all conserved.

In the absence of external torques, angular momentum is conserved.

All the options are dimensionally consistent with energy, as they can be expressed in terms of [M^1 L^2 T^-2].

Reynolds number is dimensionless as it is a ratio of inertial forces to viscous forces.

Both work and energy are measured in Joules (J) in the SI system.

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

The magnetic quantum number (m_l) can take negative values, ranging from -l to +l.

The azimuthal quantum number (l) can have a value of 0, which corresponds to an s orbital.

The principal quantum number n can never be negative; it starts from 1.

The principal quantum number (n) is always a positive integer (1, 2, 3, ...).

According to the Pauli Exclusion Principle, no two electrons in an atom can have the same set of all four quantum numbers.

The magnetic quantum number describes the orientation of an orbital in space.

The azimuthal quantum number (l) describes the shape of the atomic orbital.

The azimuthal quantum number (l) determines the shape of the orbital.

The azimuthal quantum number (l) describes the shape of an orbital.

The magnetic quantum number (m_l) describes the orientation of an orbital.

The principal quantum number n is not associated with electron spin; it describes the energy level.

The spin quantum number (m_s) does not affect the energy level of the electron.

The principal quantum number n, azimuthal quantum number l, and magnetic quantum number m_l do not describe the spin of an electron. The spin quantum number s does.

Alkynes can undergo electrophilic addition reactions due to the presence of the triple bond.
