A manometer using oil (density 0.900 g/cm3) as a fluid is connected to an air tank. Suddenly the pressure in the tank increases by 7.71 mmHg. Density of mercury is 13.6 g/cm3. By how much does the fluid level rise in the side of the manometer that is open to the atmosphere? _cm

By how much does the fluid level rise in the side of the manometer that is open to the atmosphere if the manometer used mercury instead? _ cm

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

find the surface area of the sphere to the nearest square unit. use a calculator.
