Red-shift is the increase in wavelength emitted from distant objects moving away from the observer, making them appear more red.The Big Bang Theory states that the universe began from a singularity which ...

ΔP = Δh ρ g
Δh = 1.7 - 0.5 = 1.2 m ρ = 1030 kg/m³g = 9.8 N/kg
ΔP = 1.2 (m) x 1030 (kg/m³) x 9.8 (N/kg)
= 12,112.8 N/m² = 12,112.8 Pa

To answer this, you need to pick up on the clues in the question. "Ohmic conductor" is explicitly mentioned twice, so this is likely to be important. You should know that for ohmic conductors, p...

The force exerted on a charged particle q moving with a velocity v through an electric and magnetic field, E and B respectively. F=qE+qvxB. We usually care mostly about the magnetic part. It is also worth...
