Answer:
Some things that were wrong with Rutherford's model were that the orbiting electrons should give off energy and eventually spiral down into the nucleus, making the atom collapse. Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy.

Answer:
Sublimation
Explanation:
Sublimation is when a substance goes from a solid to a gas, without going through a liquid phase. This is not a method for separation and purification.
Δt=
This because ε = dΦ/dt, and emf is a voltage so it can also be written as dΦ/dt = IR
Because ΔΦ= ABcosθ for each of the N loops and cosθ is just 1 here only A needs to be replaced, and it can be replaced with A=πr^2, which makes that part of the equation ΔΦ_m=N*B0*πa^2
