You Separate Two Magnets That Are Initially Held Together by Magnetic

question 4

Multiple Choice

You separate two magnets that are initially held together by magnetic forces. How does this affect the mass and energy of the system of magnets?

• A) It creates additional mass, located within each magnet, and also additional energy.
• B) It creates additional energy, located in the space between the two magnets, but not additional mass.
• C) It creates additional mass, located within each magnet, but no additional energy.
• D) It creates neither additional energy nor additional mass.
• E) It creates additional mass, located in the space between the two magnets, and also additional energy.

Definitions:

Zerks

Grease fittings used for the application of lubricant under pressure directly to mechanical parts, commonly found in automotive and industrial equipment.

S-Cam Actuated Brakes

A type of drum brake system where an S-shaped cam is used to push brake shoes apart and against the brake drum to stop a vehicle.

Wedge Brakes

An air foundation brake system in which an air chamber forces a wedge between brake shoes forcing them into a brake drum to effect retarding force. Wedge brakes are usually actuated on both sides (unlike S-cam brakes) and so have higher theoretical braking efficiencies.

Maintenance Costs

The expenses associated with keeping an item, equipment or property in its best operating condition, including repairs, replacements, and routine check-ups.
