(a) A proton is known to be within an interval ±6 fm (the radius of a large nucleus). Roughly what is the minimum uncertainty in its velocity? Treat this problem as one-dimensional. (b) An air-rie pellet has a mass of 20 g and a velocity of 100 m/s. If its velocity is known to an accuracy of ±0.1%, what is the minimum possible uncertainty in it's position?

Which type of microscope would allow the viewer to see ribosomes inside a cell?

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
