Explanation:
I need these pls. SORRYYY
Answer:
its point Y because the dot that represents Y is cose to s and can make a chan reaction
Answer:
J
Explanation:
The complete statement is given as
What is the maximum kinetic energy of electrons ejected from barium (Wo = 2.48 eV) when illuminated by white light, 400 nm to 750 nm ?
= wavelength of the white light = 400 nm = 400 x 10⁻⁹ m
= speed of white light = 3 x 10⁸ ms⁻¹
Energy of the white light is given as
= Work function of barium = 2.48 eV = 2.48 x 1.6 x 10⁻¹⁹ J
= Maximum kinetic energy
Using photoelectric equation we have
many increases and decreases but declined overall
