Using Coulomb's law and knowing protons are elementary charges.... F = (9x10^9)(1.6x10^-19)(1.6x10^-19) / (1)^2... Would the answer be 2.30x10-28 N?

Seems right, your turn!

Given this orientation of an operational amplifier, find the value of Rf (in kΩ) if the Vin = 20 mV, Rg = 3.8 kΩ, and Vout = 64 mV
(sorry for my bad drawing, haha)

Simplify the following logical expression in terms of only AND and OR: XOR(A, XOR(B, AND(NOT(OR(A, B)), NOT(XOR(B, NOT(AND(A, A)))))))

Oops, I forgot to specify you could use NOT too. Looks right, your turn!

Suppose you find an LED whose datasheet contains the above graph. What value resistor should you put in series with this LED and a 5V power source in order to have a current of 20 mA going through the circuit.
