The period T of a simple pendulum is given by 
where L is the length of the pendulum and g is the acceleration due to gravity. Thus if L and T are measured, we can estimate g with 
. Assume that the period is known to be T=1.5 s with negligible uncertainty, and that L is measured to be 0.559 ± 0.005 m. Estimate g, and find the uncertainty in the estimate.

Which of the following statements is false?
A. According to the Gibbs phase rule, a mixture of saturated liquid water and saturated water vapor has one degree of freedom if the water is pure, but more degrees of freedom if there are other compounds dissolved in the water. B. If the Gibbs phase rule says a system has one degree of freedom, and you specify a temperature for that system, you cannot also specify a pressure for that system—the pressure is constrained to a unique value. C. A supercritical fluid cannot be converted into a saturated vapor by an isothermal process—the pressure and temperature would both have to change. D. A supercritical fluid cannot be converted into a compressed liquid by an isobaric process—the pressure and temperature would both have to change. E. If a one-component one-phase closed system undergoes a process that is isochoric and isobaric, it must also be isothermal.
