Atrain travels 92 miles in 11 1/2 hours. what is its average speed in miles per hour?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Match each scenario to the form of energy it represents
