Harley Quinn is riding her motorbike south along a flat , horizontal road . The total weight of Harley and her hog is 1800 N. The engine exerts a 600 N force forward . The air resistance acting on Harley and the bike is 200 N. The total friction between the tires and the road is 100 N. a ) Draw a f. b. diagram for the system that includes Hayley and her motorbike.
b ) Calculate the net force on the system.
c ) Determine the mass of Hayley & her motorbike.​

The mini-refrigerator fire was most likely caused by what type of wiring?

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?

A10-kg piece of aluminum sits at the bottom of a lake, right next to a 10-kg piece of lead, which is much denser than aluminum. which one has the greater buoyant force on it? explain. b - the aluminum a) both have the same buoyant force. b) the aluminum c) the lead d) it cannot be determined without knowing their volumes.
