Which gland secretes the growth hormone (GH) in humans?

Accepted Answer

Pituitary gland

Answer

Thyroid gland

Answer

Adrenal gland

Answer

Pancreas

Question 2

A rifle fires a light bullet, resulting in a large forward acceleration of the bullet and a minimal backward recoil acceleration of the rifle. If the forces are equal and opposite (Action/Reaction), why is the rifle's acceleration so much smaller than the bullet's?

Accepted Answer

The acceleration is inversely proportional to the mass, and the rifle has a much greater mass than the bullet.

Answer

Action and reaction forces cancel out since they act instantaneously.

Answer

The reaction force of the bullet acts for a shorter duration than the action force.

Answer

The action force of the rifle on the bullet is greater than the reaction force of the bullet on the rifle.

Question 5

Which of the following is correct about force on a current-carrying conductor in a magnetic field?

Accepted Answer

The force on a current carrying conductor is proportional to the length of the conductor in the magnetic field.

Answer

The force on a conductor is along the magnetic field direction.

Answer

The force is independent of the current in the conductor.

Answer

The force depends on the resistance of the conductor.
