1. a motorcycle with a mass of 200 kg can accelerate from 0 to 30 m/s in 3 seconds. a. assuming all of the force generated by the engine goes into acceleration of the motorcycle, how much force is the engine producing? show your work. b. what would happen if the coefficient of friction between the tire and the pavement increased greatly? explain what would happen, including whether the acceleration of the motorcycle would stay the same, increase, or decrease, and tell why you think this is.

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

To fully describe the photoelectric effect, scientists must consider which of the following to be quantized? o a. both light and matter o b. matter only o c. light only o d. neither light nor matter

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
