question 1 of 3
select the best answer: the three elements of a fire make up the fire triangle. which element of the fire triangle can come from lasers and other electrical equipment?
heat
oxygen
fuel
wood

Explanation:

The fire triangle consists of heat, oxygen, and fuel. Lasers and electrical equipment can generate heat (e.g., due to electrical resistance or laser energy conversion to heat). Oxygen is typically from the air, and fuel is a combustible material (wood is a type of fuel, but lasers/electrical equipment don't provide fuel or oxygen in the context of fire initiation here). So the element from lasers/electrical equipment is heat.

Answer:

A. Heat
