Think and discuss: When the photoelectric effect was discovered, scientists were surprised that
low-frequency light was unable to remove electrons, even when the light was very bright. In other words,
scientists expected the low frequency to be offset by the light's brightness.
How does thinking about light as a stream of particles, rather than a single wave, explain this result?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
