A 3cm high fence is on the side of a hill and tends to lean over. The hill is inclined at an angle of 20o to the horizontal. A 6. 3m brace is to be installed to prop up the fence. It will be attached to the fence at a height of 2. 5m and will be staked downhill from the base of the fence. What angle to the nearest degree does the brace make with the hill?.

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
