Tilted Land is flat, much like Western Utah, but in Tilted Land gravity does not point straight down! It points down at an angle of 75 degrees with respect to the ground. (In Western Utah gravity points straight down at an angle of 90 degrees with respect to the ground.) This circumstance causes major changes in everyday life, but people manage. Suppose that a person in Tilted Land throws a ball straight up at 20 m/s. Where does the ball hit the ground?
If the density of conduction electrons is 10^27 m^3 and the wire has a radius of one millimeter, what is the electrical current through this wire
A shopper pushes a cart 39 m south down one aisle and then turns 90.0° west and moves 22 m. He then makes another 90.0° turn and moves 14 m.
