How is energy transferred from a solar panel to heat a home?

• Light energy moves from the sun to the solar panels.

• Electrical energy moves from the solar panels to the electrical converter.

• Electrical energy moves from the electrical converter to the heater.

• All of the above

What best describes the energy transfer that occurs when a baseball player hits a ball?

• The ball already has all the energy it needs when it is pitched and no energy is transferred to the ball when the batter hits it.

• The person transfers energy to the bat when he swings and then to the ball changing the ball's direction.

• The energy transfers only from the ball into the bat which then transfers into the person swinging.

• The person transfers energy straight into the ball and no energy transfers to the bat.
