1.Two buckets contain water at 30 oC. One contains 1kg of water and the other contains 2kg of water. State and explain whether the following quantities are the same or different for the water in the two buckets.
.Internal energy
.Temperature
.Average energy of a molecule
2. Briefly explain how a thermal couple can be used to measure a particular temperature of an object.

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.)
