The law of conservation of energy tells us that energy in a system is conserved. This means that the energy doesn't disappear, it's simply transformed into another form of energy or
transferred from one object to another. In the case of this simulation, the girl and her skateboard and the halfpipe are considered the system". How is the energy in this system
"conserved? If the total energy never changes, what happens to it? Be specific and explain which energy transforms into which energy. This should be detailed and in complete
sentences.

Apositive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
