## TOPIC: Vectors & Equilibrium

If line of force passes through the axis of rotation, the moment arm is

## Explanation

Moment arm is the perpendicular distance between the line of action of force and the axis of rotation. Therefore, if the line of action of force passes through the pivot point or axis of rotation the moment arm is zero.

Explanation

Study of fluids is complex, however, it is made simpler by using two conservation principles (1) Conservation of Mass (2) Conservation of Energy.

## TOPIC: Waves & Oscillations

In Hooke’s Law, F =kx, what does k represent?

Answer A:  Stiffness of the spring

Answer B: Maximum length of the spring

Answer D: Number of spirals in the spring

## Explanation

Hooke’s Law is a principle of physics that states that the force F needed to extend or compress a spring by some distance X is proportional to that distance. That is: F = kX where k is a constant factor characteristic of the spring, its stiffness.
