Question 6 a photon has an energy of 5.53 10-17 j. what is its frequency in s-1? 3.66 10-50 s-1 1.20 10-17 s-1 3.59 10-9 s-1 2.78 108 s-1 8.35 1016 s-1

For this problem, the applicable equation is that derived by Max Planck

E = h * frequency where E is the energy of the photon, and h is the Planck’s constant which has a value of 6.626 x  J-s.

Upon substituting,

5.53 x  J = 6.626 x  J-s * frequency

Frequency = 8.35 x  

The answer is 8.35 x  .

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
