What is the smallest angle over which we can tell two objects (like stars) apart as distinct? Diffraction resolution

Spectroscopic limit

Angular resolution

Refraction resolution

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

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is
