ANSWERS
1. The correct answer is C. Jupiter has 16 moons.
2. The correct answer is A,B, and C. All are correct. Sunlight enters the car through the windows because light waves are strong enough to go through glass. When the interior of the car absorbs the light, it changes into heat. The heat waves, being weaker than light waves, cannot penetrate the window and therefore become trapped.
3. The correct answer is B- Alexander Volta. That's where the word "voltage" comes from!
