A ping-pong ball is moving at 7.55 m/s at right angles to Earth’s 44.0 μT magnetic field. How much charge would you need to put on the 2.70 g ping-pong ball so that the magnetic force on the ball is equal in magnitude to the gravitational force on the ball? Assume g = 9.80 m/s2 . Note: The charge is unrealistically large!

State the following: boyle's law and charle's law

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
