<span>The centripetal force that keeps the lady bug moving in a circle is FRICTION. The Centripetal Force</span><span> is a net force acting on an circling object that sustains constant circular motion. </span>It opposes the motion by acting in opposite direction. A ladybug sits at rest on a turntable that is rotating, during this motion, the ladybug's acceleration vector points <span>toward the center of the turntable.</span>
Kinetic Energy is the energy of motion, this means whatever letter(s) show the ball moving it's fastest is it's maximum Kinetic Energy
Answer:
C. magnetic force
Explanation:
A magnetic field is responsible for the magnetic forces acting on a moving charge, so we can say that the direction of the magnetic field is determined by the magnetic forces. In the case of a conductor traversed by electric current and subjected to the presence of a magnetic field, we will also have the action of a magnetic force, since the current represents an orderly movement of electric charges.
An example of the application of magnetic force occurs in the TV tube, where a set of coils (artificial magnets), with their magnetic fields, enables the action of magnetic forces that deflect electron beams, causing them to traverse the entire screen. These electron beams sweep the phosphor-coated screen, line by line, from left to right and top to bottom, allowing the image to emerge.
Electromagnetic waves about the size of a golf ball are used for
microwave radio communication and radar every day.
Electromagnetic waves that are about 4-1/2 inches long are used
in the microwave oven to heat leftover meatloaf and make popcorn .
Electromagnetic waves that are 10 times the size of an atom
are hard hard X-rays.
Electromagnetic waves that are the size of Earth's diameter
are used for ELF communications, including standard time
signals, and submarine communication.
Mechanical waves that are the same order of magnitude as
the Earth are seismic (earthquake) waves.
Gamma rays are electromagnetic waves with wavelengths in the
neighborhood of the same size as the atomic nucleus. To get
some idea of their frequency, just contemplate how long it would
take light ... (which can get to the moon in a couple of seconds) ...
to move from one side of an atomic nucleus to the other side.
