The wavelength of a light wave can be used to measure which of the following?
a: how many photons the wave contains
b: how high the top of the wave is
c: how much energy the wave has
d: the direction the wave is traveling

Why are gamma rays not affected by a magnet as they pass over it? gamma rays are composed of only energy. gamma rays do not have enough mass to be affected. gamma rays do not have the right electrical charge to be affected. gamma rays move too fast for anything to affect their pathway.

An unknown insoluble substance displaced the water shown. it's mass is indicated on the triple beam balance. mass = a. 694 b. 693.5 c. 693.0 d.693.8

Suppose you discovered a new element with 120 protons and 2 electrons in its outer level . i'm what group does this new element belong? what properties would you expect it to have
