Ahot metal bowl is placed on a wooden table. over time, the wood becomes warm. which of these statements best describes why the table becomes warm? collisions between the metal and the wood raise the kinetic energy of the wood molecules. the heat from the metal produces convection currents within the wood molecules. the kinetic energy of the metal molecules increases due to radiation. convection between the metal and the wood increases the motion of the wood molecules.

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?

According to the image below, which season is about to begin in the southern hemisphere? a. summer b. autumn c. winter d. spring

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
