The propeller of an aircraft rotates clockwise as seen from the rear. When the pilot pulls upward out of a steep dive, she finds it necessary to apply left rudder at the bottom of the dive if she is to maintain her heading. Explain.

The rudder allows the pilot to control the horizontal direction of the aircraft. Appling the left rudder would turn the aircraft along its horizontal direction such that the aircraft appear to move in counter-clockwise direction when observed from the rear. This is necessary to pull the aircraft upward from the steep dive when the propeller of the aircraft rotates clockwise because it balances the torque experienced by the aircraft when turns and prevents rolling or wobbling.
It is important to note that the left rudder provides a counterbalancing torque to the torque experienced by the clockwise rotation of propeller blades.
