Question | Answer |
---|---|
velocity in rotational motion | v = 2πr / t |
Rate of Heat Transfer | H = (k A ΔT) / L k = thermal conductivity A = Cross sectional area L = Distance Between ends |
Heat Input | QH= QL + W QL= Heat Flow out |
Change in Entropy | ΔS = Q/T Q= Heat added |
Change in Internal Energy | ΔU = 3/2 NkΔT |
Electric Field 2nd | E = k Q / r^2 |
Magnetic Field Inside a Solenoid | B = μo n I μo = Vacuum Permeability Only if air is in the solenoid, if there is something else use μ which is magnetic permeability n= number of loops per unit length I = Current |
Energy with wavelength | E = hc / λ |
