Answer:

C) a potential difference across its ends.

Explanation:

We know , according to Ohm's law, at a constant temperature, current flows through a circuit is directly proportional to the voltage applied.

                   V=I\times R    Here R is resistance provide by circuit.

                   I=\dfrac{V}{R}.

Also, currents flows in the opposite direction of electrons. If current flows then only electron flows.

From Ohm's law , current flows only when their is a potential difference.

Therefore, same goes with electrons as they flow only when current flows electrons.

C) Option is correct.

Explain the relationship between temperature, energy, and motion of particles in an object.
ANEK [815]

Answer:

Explanation:

Temperature is the degree of hotness or coldness of a body.

Energy is the ability to do work by a body. They are of two forms, potential and kinetic energy. Potential energy is due to the position of a body whereas kinetic energy is due to the motion of a body.

Motion is the change in position of a body with time.

Temperature, energy and motion are all related.

Thermal energy is a form of kinetic energy which is concerned about the motion particles. This form of energy results from heat changes in a body which causes temperature differences.

When a body is heat and changes temperature, the particles begins to vibrate as they gain, thermal energy, a form of kinetic energy. At a point, the particles will break lose and set in motion.

Andrews [41]
We use Lenz's law:
emf = -(NBA)/t ; N is the number of turns, B is the magnetic field, A is the area
t = 1/f = 1/10
emf = (-100 x 0.05 x 0.1) / 0.1
emf = -5 V
