1 FINAL EXAM CHEM 219 EXAM | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ The speed of a wave (c) is the product of its frequency (ν) and wavelength (λ). Correct Answer: E = hv = h x c / λ nm to m or m to nm Correct Answer: 1 m / 10^9 nm or 10^9 nm / 1 m What is the maximum number of electrons that can have the quantum numbers n = 3, ℓ = 2, mℓ = -2? Correct Answer: The Pauli exclusion principle states that no two electrons in a given atom can share the sa...

equilibrium means no acceleration, which means a constant velocity. - Answer-Friction should be thought of as opposing sliding. the board is "perfectly balanced." Whenever you see this on the MCAT, you know the net torque must be zero. - Answer-torque/fulcrum/pivot point situations, if there is no rotation, there is NO NET TO RQUE When you see "average force " on the MCAT, it is a dead give away that it will be dealing with work (W = Favgdcos0). - Answer-to think of power a s P = ΔE...
