A charged particle is injected at 265 m/s into a 0.0891 ‑T uniform magnetic field perpendicularly to the field. The diameter of its orbit is measured and found to be 0.0383 m. What is the charge–to–mass ratio of this particle?

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

The slope of a velocity time graph over any interval of time gives the during that interval
