Complete the passage to describe polarization.
unpolarized light is filtered by a polarizer that has a vertical plane, allowing light with oscillations to pass through and blocking light that oscillates in other directions.
then, another polarizer that has a plane is used to block the polarized light.

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

Abatter hits a 0.140-kg baseball that was approaching him at 30 m/s and, as a result, the ball leaves the bat at 40 m/s in the reverse of its original direction. the ball remains in contact with the bat for 2.0 ms. what is the magnitude of the average force exerted by the bat on the ball?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
