Apendulum clock with a pendulum made of brass is designed to keep accurate time at 29°c. if the clock operates at 0.0°c, (a) does it run too fast or too slow, and (b) what is the magnitude of its error, in seconds per hour (use a minus sign to indicate slowing down)? the linear expansion coefficient of brass is 19 × 10-6 /c°.

Need in all of themmm only answer if you know plsssss

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s.a. determine jay’s mass.b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
