Explanation

When two bodies are moving in opposite directions, their velocities are added to find the relative velocity.

Let's say the velocities of the two bodies are v1 and v2.

Relative velocity = v1 + v2

Since both velocities are non-zero and in opposite directions, the relative velocity will be greater than the absolute velocity of either body.

So, the statement "Relative velocity > Absolute velocity" is true.

Explanation

The average translational kinetic energy of a molecule is given by:

(3/2)kT = (3/2) × (1.38 × 10^-23 J/K) × T

Since the temperature is the same for both O2 and N2 molecules, the average translational kinetic energy will be the same:

0.048 eV = (3/2)kT

The mass of the molecule does not affect the average translational kinetic energy.

Therefore, the translational kinetic energy of N2 molecules at the same temperature is also:

0.048 eV

Explanation

To find the work done, we need to integrate the force with respect to the displacement.

Given:

F(x) = 7 - 2x + 3x^2 N

x_initial = 0 m

x_final = 5 m

Work done (W) is the integral of force (F) with respect to displacement (x):

W = ∫[x_initial, x_final] F(x) dx

= ∫[0, 5] (7 - 2x + 3x^2) dx

Evaluating the integral:

W = [7x - x^2 + x^3] from 0 to 5

= (7(5) - 5^2 + 5^3) - (7(0) - 0^2 + 0^3)

= (35 - 25 + 125) - 0

= 135 J
