What is the potential energy at the end of the loop? what is the kinetic energy at the end of the loop (based upon the photogate time) I PUT THE TIME ON THE PICTURE? oh also can you help me find the speed of the car at the bottom of the hill like i know speed is distance multiples by time but i don’t know what number to use for distance.. the same picture shows some data i just don’t know how to use it. thanks would be greatly appreciate

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

What type of force holds atoms together in a crystal?

Aphase diagram assumes is kept constant.
