E = energy in the light rays = h ν = h c /λ = 6.67 * 10×⁻³⁴ * 3 * 10⁸ / (5.84*10⁻⁸) J = 3.42 * 10⁻18 JKinetic energy of electrons = 1/2 m u^2 = 1/2 * 9.1 * 10⁻³¹ * (2.45 * 10⁶)² J = 2.73 * 10⁻¹⁸ J The ionization energy = (3.42 - 2.73) * 10⁻¹⁸ J = 6.9 * 10⁻¹⁹ J
Answer:
Describing Describe the general process by which new elements are synthesized.
Albert Einstein's work focused on relativity theory and the as it could be applied to gravity, quantum mechanics and the theory of light.
<h3>Who is Albert Einstein?</h3>
The physicist Albert Einstein was born in Ulm Württemberg Germany in 1875. He migrated to the United States at the height of the Nazi regime in Germany where he became a professor of physics at Princeton University.
His work focused on the relativity theory and the as it could be applied to gravity, quantum mechanics and the theory of light. These ideas still remain fundamental in science today.
I became interested in the work of Albert Einstein because of the fact that is work is fundamental to the understanding of quantum mechanics and the idea of gravity. He laid the foundation upon which modern physics is built.

Answer:
Answer is d, strength of London forces increases with molecular size.
Explanation:
Dispersion forces are the forces preesnt between all intermingling atoms, molecules and particles. Dispersion forces are the weakest intermolecular force, but they build up with the addition of more atoms, molecules or particles. Heat of vapourisation or boiling point is dependant on the energy required to break the bonds within the molecule/hydrocarbon in question. The build up of dispersion forces create greater intermolecular forces, which make the boiling of a substance more difficult. Hence increased hydrocarbon chain length, and the related increased eat of vapourisation is due to how the strength of the London/Dispersion forces increases with molecular size
