Answer 3

The number of electrons emitted would increase.

Answer 4

the speed of the electron depends on the frequency or energy applied to the electron to displace it form the metal

Answer 5

youre the best!! @dan815

Answer 6

when the light remains blue, the frequency of the light is the same, but when there are 2 sources there is more light so more electrons can be hit, but they will always eject at the same energy level
