Imagine a particular exoplanet covered in an ocean of liquid methane. At the surface of the ocean, the acceleration of gravity is 4.70 m/s2, and atmospheric pressure is 8.60 ✕ 104 Pa. The atmospheric temperature and pressure on this planet causes the density of the liquid methane ocean to be 415 kg/m3. (a) What force (in N) is exerted by the atmosphere on a disk-shaped region 2.00 m in radius at the surface of the ocean? N (b) What is the weight, on this exoplanet, of a 10.0 m deep cylindrical column of methane with radius 2.00 m? (Enter your answer in N.) N (c) What is the pressure (in Pa) at a depth of 10.0 m in the methane ocean

Can you please help me whith this question? Thank you so much!

The free-fall acceleration on the surface of a fictional planet is about 1/2 that on the surface of the Earth.. The radius of the planet is about 0.71RE (where we use the symbol RE = Earth's radius). Find the ratio of their average densities, pp/Pɛ. Please feel free to look up the earth"s radius in the table in your text-book.

common belief is that a hole in a jet plane can suck a person out. On an episode of a popular TV series, the hosts attempted to determine whether this is possible. According to the hosts' experiment, such an event cannot happen. Did they need to perform the experiment? As a science adviser to the show, the hosts ask you to perform a crude calculation to test the myth. A typical jet plane travels at 532 mph at a cruising altitude of 30500 ft. The windows on a jet plane measure 14.0 in × 14.0 in. Calculate the force ? exerted on such a window as the plane flies at 30500 ft above the sea level. Assume the density and pressure of air at 30500 ft are 0.452 kg/m3 and 292 mbar, respectively, but that the interior of the plane remains pressurized to atmospheric pressure, 1 atm.   Calculate the fractional difference between this force and the weight ?man of a typical adult male (185 lb).     How would you respond to Adam and Jaime? a)There is no need to perform the…

The specific gravity of honey is 1.44. A cylindrical container of honey 10 feet​ [ft] deep is inside a dome pressurized to a surface pressure of 0.06 atmospheres​ [atm] on the surface of Pluto. The total pressure at the bottom of the container is 65 millimeters of mercury​ [mm Hg]. What is the gravitational acceleration of​ Pluto, in units of meters per second squared m/s2​?

You are preparing some apparatus for a visit to a newly discovered planet Caasi having oceans of glycerine and a surface acceleration due to gravity of 5.40 m/s2. If your apparatus floats in the oceans on earth with 30.0 % of its volume submerged, what percentage will be submerged in the glycerine oceans of Caasi?

On February​ 15, 2013, Asteroid 2012 DA14 passed within​ 17,200 miles​ [mi] of the surface of the Earth at a relative speed of 7.8 kilometers per second​ [km/s]. This is considerably closer than the orbit of geosynchronous satellites​ (26,200 miles). This is the closest recorded approach of an object this large. The asteroid 2012 DA14 was estimated to have a diameter of 30 meters​ [m] and a specific gravity of 3. If 2012 DA14 had hit the​ Earth, what is the total amount of energy that would have been released​ (i.e., what was the kinetic energy of the​ asteroid)? Express your answer in megatons​ [Mton]. One megaton is the energy released by one million metric tons of TNT explosive. A metric ton equals​ 1,000 kilograms​ [kg], and the explosive energy of TNT is 4,184 joules per gram​ [J/g].
