Answer 2

The normal force in this scenario is the force exerted by the table on the brick to support its weight and prevent it from falling through the table. Since the brick is not moving, the normal force must be equal in magnitude and opposite in direction to the force of gravity acting on the brick.

The force of gravity can be calculated using the formula F = m * g, where m is the mass of the brick (30 kg) and g is the acceleration due to gravity (approximately 9.81 m/s^2).

F = 30 kg * 9.81 m/s^2 F = 294.3 N

Therefore, the normal force acting on the brick is also 294.3 N, directed upward to support the weight of the brick and keep it from falling.
