When you take off a wool hat, some of the electrons from your hair transfer to the hat. When this happens, your hair can stand up on end. Why doesn't
gravity hold your hair down?
A. The distance to the center of Earth is vastly larger than between
the hat and your hair,
B. The electrical field caused by the charged hair disrupts the
gravitational field near your hair
C. The electrostatic force is stronger than the gravitational force
between Earth and your hair,
D. The gravitational force between the hat and your hair opposes
Earth's gravitational force,

C. The electrostatic force is stronger than the gravitational force

between Earth and your hair

Explanation:

Electrostatic forces are extremely strong. When your hair becomes charged from the electrons, it causes the strands of your hair to repel (push away) from each other because they have like (the same) charges.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
