A civilian space traveler lands on an alien planet. A pendulum (L = 0.250 m) is used to find the gravity of the planet. The following graph is provided. Answer the questions based on this information. 1. What is the period and frequency of the pendulum’s motion? Explain or show your work.
2. What is the acceleration due to gravity on the surface of the planet in?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
