A roller coaster needs more kinetic energy to reach the top of a tall Hill what are two ways that the engineer can increase the amount of kinetic energy the roller coaster has

Explanation:

So a roller coaster the best way is to start at the top of a hill so that the coaster has enough energy to go up the next hill

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
