A centrifuge rotor rotating at 9500 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 1.19 m. N. Part A If the mass of the rotor is 3.67 kg and it can be approximated as a solid cylinder of radius 0.0900 m, through how many revolutions will the rotor turn before coming to rest? Express your answer to three significant figures. N V ΑΣΦ Submit Part B Request Answer Ć How long will it take? Express your answer to three significant figures and include the appropriate units. ?

I Review I Constants You are designing a rotating metal flywheel that will be used to store energy. The flywheel is to be a uniform disk with radius 35.0 cm. Starting from rest at t = 0, the flywheel rotates with constant angular acceleration 3.00 rad/s? about an axis perpendicular to the flywheel at its center. Part A If the flywheel has a density (mass per unit volume) of 8600 kg/m³, what thickness must it have to store 800 J of kinetic energy at t = 8.00 s? Express your answer with the appropriate units.

C. The radius of revolution for the microcentrifuge is 8.58 cm and you need to spin at 700g. What RPM should you spin at?

Pls help ASAP.

You are installing a new spark plug in your car, and the manual specifies that it be tightened to a torque that has a magnitude of 39 N·m. Using the data in the drawing, determine the magnitude F of the force that you must exert on the wrench. N

consider the figure above. consider the small block (M). let say that this inverted cone is rotating vertically or a vertical axis. lets say that the angular speed of this is Vtangential = = r*@ coefficient static friction (block and xone) = Hs. LETS SAY we need to remain this block at its height while spinning (radius of revolution = h*tan theta), FIND: a. Max value of b. min value of

A merry-go-round accelerates from rest to 0.70 rad/s in 30 s.     Part A Assuming the merry-go-round is a uniform disk of radius 8.0 m and mass 3.20×104 kg , calculate the net torque required to accelerate it. Express your answer to two significant figures and include the appropriate units.
