Describe how thermal energy is transferred through radiation

The thermal motion of their particles spreads into your body. But there are different ways for that heat to transfer: It can transfer by conduction, convection, or radiation. Conduction is the transferring of heat by direct contact. Convection is transferring heat through the motions of fluids (gases and liquids).

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
