To solve a problem using the equation for kepler’s third law, enrico must convert the average distance of mars from the sun from meters into astronomical units. how should he make the conversion? multiply the average distance by 1.5 × 1011 multiply 1.5 × 1011 by the average distance divide the average distance by 1.5 × 1011 divide 1.5 × 1011 by the average distance

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

By what primary heat transfer mechanism does the sun warm the earth?

Arailroad car collides with and sticks to an identical railroad car that is initially at rest. after the collision, the total kinetic energy of the two cars is a) the same as before. b) half as much as before. c) one third as much as before. d) one fourth as much as before. e) twice as much as before.
