Two events occur in an inertial system k as follows. event 1: x1 = a, t1 = 2a/c, y1 = 0,z1 = 0event 2: x2 = 2.6a, t2 = 1.5a/c, y2 = 0,z2 = 0what is the velocity of the frame k' in which these events appear to occur at the same time? express the velocity vector using the variables a and c and the unit vectors, i, j, and k; for example, 2i + 2j is a vector which bisects the x and y axes.

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

Consider an ideal gas at 27.0 degrees celsius and 1.00 atmosphere pressure. imagine the molecules to be uniformly spaced, with each molecule at the center of a small cube. what is the length l of an edge of each small cube if adjacent cubes touch but don't overlap?

Which of the following is not a means to accelerating? question 4 options: a)increase speed b)remain still c)decrease speed d)change direction
