\fSuppose a roulette wheel is spinning at 1.0 rev/s. How much time t does it take for the wheel to come to rest if it experiences a constant angular acceleration of 0.030 radfsz'? How many rotations, N , does it complete in that time? A door with a width w = 89.0 cm is pushed open with a force F of magnitude 65.0 N. a b C d + + + + 750 Hinge F axis 20 Calculate the magnitude of the torque ra about an axis through the hinges in Case (a). Ta = N.m Calculate the magnitude of the torque ah about an axis through the hinges in Case (b). Th = N.m Calculate the magnitude of the torque to about an axis through the hinges in Case (c). To = N.m Calculate the magnitude of the torque ra about an axis through the hinges in Case (d). Ed = N.mAn electron in the n = 2 energy orbital of the hydrogen atom has an angular momentum of magnitude 2.109 X 10'34 J-s and an orbital radius 0f2.117 X 10"" m. The electron's mass is 9.11 X 10'31 kg. What is the electron's speed 0 in this orbital
