What if? the east end of the rod impacts and sticks to a pylon, causing the rod to rotate clockwise as viewed from above. while the rod rotates, what is the magnitude of the induced emf between the ends of the rod (in mv)? (hint: use conservation of angular momentum to find the speed of the rod after the collision.)

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

A100-watt light bulb illuminates a solar cell. the electricity from the solar cell operates a water pump that delivers 1 watt of power. what is the efficiency of the system?

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
