Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.489×10−3 m3/s0.489×10−3 m3/s and the diameter of the nozzle you hold is 5.91×10−3 m.5.91×10−3 m. At what speed vv does the water exit the nozzle?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
