Question

nonmetals are poor ________ of both heat and electricity. a conductors b emitters c reflectors d transmitters

Explanation:

In the context of physics (a subfield of Natural Science), nonmetals are known to be poor conductors of heat and electricity. Conductors are materials that allow heat or electricity to pass through them easily, while nonmetals lack this property. Emitters are related to emitting (e.g., light, particles), reflectors reflect (e.g., light, heat), and transmitters transmit signals (not related to heat/electricity conduction). So the correct term is "conductors".

Answer:

A. conductors
