A student holds a bike wheel and starts it spinning with an initial angular speed of 7.07.0 rotations per second. The wheel is subject to some friction, so it gradually slows down. In the 10.0 s10.0 s period following the inital spin, the bike wheel undergoes 60.060.0 complete rotations. Assuming the frictional torque remains constant, how much more time ΔtsΔts will it take the bike wheel to come to a complete stop?

The momentum of an isolated system is conserved a) only in inelastic collisions. b) only in elastic collisions. c) in both elastic and inelastic collisions

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

(01.02 mc) nicole pushes her bike up a hill. overhead, the sun exerts a gravitational force on earth. which statement is true about the bike and earth? they both experience contact forces. they both experience non-contact forces. the bike experiences a non-contact force and earth experiences a contact force. the bike experiences a contact force and earth experiences a non-contact force. they both experience non-contact forces.
