A chef spins a disk of pizza dough over her head, giving it an angular speed of 7.0 rad/s. If the moment of inertia of the pizza dough is 6.3 ×10−6kg⋅m2, what is its rotational kinetic energy? (Assume that the disk of dough is uniform.)

Explain in physical terms how a microwave oven works. what would happen when you put a conductor in the microwave oven? explain.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

In what direction does the medium move relative to the direction of the wave? explain.
