Answer:

The kinetic energy will remain constant

Explanation:

Charged particles in a magnetic field feel a force perpendicular to their velocity,  since the force is F = qvB, and a charged particle feels a force of constant magnitude always directed perpendicular to its motion which causes circular motion in the magnetic field but the speed and kinetic energy of the particle will remain constant.

Therefore, if only the magnetic field acts on the particle, its kinetic energy will remain constant.

In what direction does centripetal force act on an object that is traveling in a circular path?
Setler [38]

According to Newton's first law of motion, it is the natural tendency of all moving objects to continue in motion in the same direction that they are moving ... unless some form of unbalanced force acts upon the object to deviate its motion from its straight-line path.

Hope this helped, have a great day!

Name three types of energy that exist in a large piece of charcoal on a grill in the sunlight. Explain why the charcoal has each
qaws [65]

Answer:

A large piece of charcoal on a grill in the sunlight (if it's burning) will consist of the following types of energy:

  1. Chemical
  2. Heat and
  3. Light

Explanation:

Charcoal is basically carbon which is produced when wood is heated strongly in the absence of oxygen. From a chemistry point of view, charcoal contains combustible carbon whose chemical formula is C. Sometimes, H_{2}O which is water may be found in it but in very small units.

All matter contains Heat energy. Charcoal is not an exception. As the charcoal burns, the heat energy is produced along with Light energy.

Light comes in many forms such as Infrared rays, Xrays, Visible Spectrum light, etc.

The glow which the coal gives off fall under the visible spectrum of light.

Cheers
