what is the total resistance of 2 resistors each with resistance 2 ohms in parallel?

1/R t = 1/R 1 + 1/R 2 The equation for resistors in parrallel. If R 1 and R 2 are both 2 ohms then 1/R t = 1/2 +1/2 = 1 so R t = 1 ohm. Note: Don't forget the units at the end.

How, given the threshold frequency and the kinectic enery of a photon, do you determine the frequency of the phton?

You can use E= hf o + KE and E=hf (Einstien's equations) to work how the frequency of a photon, where f o is the threshold frequency and h is Planck's constant.

Find the x coordinate of the minimum point of the curve y = e3x - 6e2x + 32.

To find the minimum point of this curve you need to differentiate y and set it equal to zero before solving for x. If the questions does not say otherwise give your answer to 3 s.f. dy/dx = 3e^3x -12e^2x = 0...
