In what order were the following energy sources discovered by humans? Biomass energy was discovered first; then fossil fuels, then fuel cells
O Fossil fuels were discovered first, then fuel cells, then biomass energy
O fuel cells were discovered first; then fossil fuels, then biomass energy
Biomass energy was discovered first, then el cells, then fossil fuels

i think they are all correct

explanation:

they seem good

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

neither accurate nor precise.
