Lets say you watched a man run and knew the mass ( m )and the velocity ( V ) of the man and then calculated the momentum and your answer was p. The man then runs for a second time and his mass stays the same ( m ) but this time his velocity was twice as fast ( 2V ). What is his new momentum after the 2nd run?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

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?

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
