How can heat be transferred?

a. convection, ultraviolet rays and conduction

b. convection, gamma rays and conduction

c. convection, visible light and conduction

d. convection, radiation, and conduction

D because gamma rays and ultra violet rays are one of the examples of the three ways to transfer heart which is convection, radiation, and conduction.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
