Answer: 1: kinetic energy and velocity are at zero when the magnets are held apart, and both increases rapidly when they are released and move together. Energy stored in the magnetic field decreases.
2: The energy stored in the system is converted to kinetic, thermal, and sound energy.
3: The energy stored in the magnetic field does not change.
4: Some of the energy stored is converted into kinetic and thermal energy.
5: Two small repelling magnets hold each other in place.
Just took the quiz all are correct! I hope this helps you! :)
Answer:
The arrows always start at the magnet's north pole and point towards its south pole. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).
1. growl: most certainly the dog is going to start growling, but not in a negative, aggressive way, but rather in a surprised, amused way
2. li.ck: the dog will definitely li.ck you, as this is what dogs do when approached
3. pant: dogs pant all the time, especially if it's hot outside, so hugging them makes no difference
4. play: they will want to play with you once they see you love them and want to be around them
5. try to run: some dogs aren't really into hugging, which is why they will try to run away from you because they are confused
Answer:
The water acts like a lubricant therefore has a smooth motion over the ice.
Answer:
Explanation:
Given the initial velocity of the clown, his mass and final height we can calculate the final kinetic energy using the <em><u>conservation of total mechanical energy</u></em>
Since
