a. 40 radiate in
c. 5 radiate out
b. 20 radiate out

On a PV diagram representing an isothermal compression, what is the relationship between the initial P value and the final P value?
A. The initial is greater than the final B. The initial is less than the final C. They may be either – it depends on the temperature of the process D. They may be the same.
Coulomb's Law: Two point charges q = -8.50 µC are fixed 10.0 cm apart along a horizontal bar, as shown in the figure. Their electrical forces will be used to balance the weight of a very small sphere carrying a charge Q = + 15.0 ?C, 10.0 cm from each of them in a place where g = 9.80 m/s2. What is the greatest mass M this sphere can have without falling? (k = 1/4??0 = 8.99 × 109 N ? m2/C2)
