A simple pendulum named Bob has a period of small oscillations T=1 s on Earth (assume g=9.80 ms2{“version”:”1.1″,”math”:”ms2″} ).  Bob is flown to a planet X and it is found that now its’ period of small oscillations is 2 s. What is the value of specific gravity on the planet X in  m / s 2 {“version”:”1.1″,”math”:”\mbox{m}/s^2″}?

Which of the following statements are true? A decrease in production will ordinarily result in a decrease in fixed production costs per unit. If the activity level increases, then one would expect the fixed cost per unit to decrease. A fixed cost is a cost whose cost per unit varies as the activity level rises and falls.
