A Level is set up midway between two wood hubs that are about 300 ft. apart. The rod reading on hub A is 9.09 ft. and the reading on hub B is 5.65 ft. The level is moved so it is along the side of hub B and about 6 feet away from it. Readings are taken are taken from the new set up with the reading on hub A of 7.11 ft. and on hub B of 3.70 ft. (10 points) (see Section 2.11) a. What is the correct difference in elevation between the hubs A and B

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
