Question | Answer |
---|---|
Centripetal Acceleration | ac = v^2 / r |
Moment of Inertia | I= mr^2 |
Rotational Velocity | w = 2πf |
Power (2nd) | P= Fv |
Root mean Squared velocity | v rms = √(3 k T / m) |
Change in Internal Energy | ΔU = 3/2 NkΔT |
Ideal Efficiency | e = TH-TL / TH |
Change in Entropy | ΔS = Q/T Q= Heat added |
Wavelength in a double slit experiment | λ = dx/ mL d= separation of the slits x= position of the fringe at m m= integer ( fringe order) L = Distance from slit to screen |
Input energy of a Photon for the photoelectric effect | hf= KE + φ φ= work function (energy needed to get the electron out of the metal) |
Wavelength (Atomic) | λ = h/p p= momentum |
Energy with Wavelength | E = hc/ λ |
Angular Momentum | L = mvr = nh/ 2π n = 1, 2, 3,... r= radius of the nth possible orbit |
