2. Turn off the Parallel line and turn on the Line through focal point. Move the light bulb around. What do you notice about the reflected ray in this situation?

Determine the maximum r-value of the polar equation r =3+3 cos 0

What will a positive and a negative charge do if they are separated from each other?

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j
