Answer:
Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Explanation:
It depends on "Potential Energy", the amount energy it could have, the amount depending on certain circumstances, like height or force. This was how traditional and some modern rollercoasters work. As the "conveyer belt" pulls you up, the higher you go, the more potential energy you have. Once you are falling down the hill, you are experiencing "Kinetic Energy". Hope it makes sence.
True. If something is thermal, that means that by getting to close to it, you could get burned.
Answer:
B Explain why the relationship between force and time is important to a helmet designer.
During a collision, a skater will suddenly come to a complete stop. This is a foam of acceleration. A helmet can change the amount of
