PLZ HELP!! I NEED THIS ANSWERED FOR A QUIZ! A neutral rubber rod is rubbed with fur and the rod acquires a charge of -2.0 x 10-6 coulombs. Therefore, the fur:
lost 2.0 x 10-6 electrons
gained 2.0 x 10-6 protons
O gained 1.25 x 1013 protons
lost 1.25 x 1013 electrons

Asuppose a suitcase has a mass of (m) 30 kg and a net force (n) of 10 kg*m/s. what is the acceleration rate of the suitcasein m/s? show your work to support your answer.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
