Which of the following best describes the use of a non-renewable resource? Nuclear energy heats water into steam that turns the turbines of a power plant. Water falls through openings in a dam turning turbine blades that generate electricity. Wind turbines gather energy from the wind and convert it into electrical energy. The electronic signs along the highway are run by solar power.

Explanation:

water falls through openings in a dam turning turbine blades that generate electricity

Nuclear energy ... non-renewable.  It uses up the Uranium, and then we have to dig more Uranium out of the ground.

Water falling ... renewable kinetic energy, as soon as the sun lifts the water back up into the sky, and then it falls intk the lake again, and runs through the turbines again.

Wind turbines ... renewable kinetic energy, as soon as the sun heats the world unevenly again, and winds blow again.

Electronic signs run by solar power ... the solar power shines down on us, and will continue doing that for a few more billions of years, whether we use it or not.  So we don't use up the sun by grabbing some of that energy.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

c) up is the direction the magnetic force is acting on the charge.
