Radiation transfers thermal energy through?
a)waves
b)direct contact
c)particles
d) liquid movement?

A)waves

Explanation:

In radiation mode of heat transfer we do not require any medium to transfer energy from one point to other.

Here in radiation mode of heat transfer energy is being transferred by electromagnetic waves in which energy is propagated in form of electric field and magnetic field energy.

here the electromagnetic waves will travel at the speed of light and it is the fastest mode of heat transfer

so here the correct answer will be

A)waves

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
