A hollow sphere (M = 7.69 kg, R = 0.

/in /by

A hollow sphere (M = 7.69 kg, R = 0.648 m) is rolling without slipping on a horizontal surface with its center of mass moving at linear speed vo when it comes to a rising incline that makes an angle of = 33.7o with the horizontal. The ball now rolls without slipping up the incline. a) Find a, the magnitude of the linear acceleration of the ball on the incline. m/s2 b) Find f, the magnitude of the force of static friction exerted by the incline on the ball. N c) If the ball rolls distance d = 2.8 m up along the incline before coming to rest: find vo, the initial linear speed of the ball. m/s

pipe x of length 3m is open at both ends. it produces a note of frequency 28Hz when the air in the pipe vibrates in its fundamental (first harmonic) mode. Pipe y is closed at one end and also produces a note of frequency 28Hz when the air in the pipe vibrates in its fundamental mode. The best estimate for the length of pipe y is

You are examining a nerve cell preparation.

You are examining a nerve cell preparation. The equilibrium potential for potassium under the current circumstances was at -80 mV, the equilibrium potential for sodium was +60 mV and the resting potential was -70 mV. A new chemical is added which increases the sodium conductance by a factor of 2. What would be the effect of decreasing the internal potassium concentration by a factor of 2 on the resting potential and excitability of the cell?

A boat has an initial velocity of 2 m/s in the y direction on a stream which is moving in the x direction at 1 m/s. The boat is accelerating in its direction of motion at 1 m/s2. What is the acceleration of the boat (in m/s2) relative to the water? Answer is 1j.

If you want a superhero that runs really fast, you turn to the Flash. But being able to run fast also means you have to have friction.

If you want a superhero that runs really fast, you turn to the Flash.  But being able to run fast also means you have to have friction.  What might be the frictional force required for the Flash to run as fast as he does?  And what about the frictional force required to stop?  Again making some reasonable assumptions, discuss how you would answer these questions.
