What is the function of the muscles around the lens in the human eye? They send signals to the brain.
D They control the amount of light that passes through the lens.
They focus light rays onto light-sensor cells at the back of the eye.
They change the shape of the lens.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

What is a costume plot? why is it important to a film or theater production?

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.)
