(a) What is the strength of the weak nuclear force relative to the strong nuclear force? (b) What is the strength of the weak nuclear force relative to the electromagnetic force? Since the weak nuclear force acts at only very short distances, such as inside nuclei, where the strong and electromagnetic forces also act, it might seem surprising that we have any knowledge of it at all. We have such knowledge because the weak nuclear force is responsible for beta decay, a type of nuclear decay not explained by other forces.

Interaction between an electric field and a magnetic field.
The force that is exerted on an object by any surface which is in contact and that which acts perpendicular to the surface of contact is known as
a. Normal forceb. Contact forcec. Friction forced. Gravitational force
What net external force is exerted on a 1400-kg artillery shell fired from a battleship if the shell is accelerated at 300×104 m/s22.40×104 m/s2? What is the magnitude of the force exerted on the ship by the artillery shell?
According to Newton's third law, every force is accompanied by an equal and opposite reaction force. The reason that these forces do not cancel each other is ____.
a. the action force acts for a longer time period
b. the two forces are not always in the same direction
c. one of the two forces is greater than the other
d. the two forces act upon different objects; only forces on the same object can balance each other.
e. ... nonsense! They do cancel each other. Objects accelerate because of the presence of a third force.
