What is the si unit for pressure? ?

Pascal (Pa)

Explanation:

The pressure is a scalar physical magnitude that measures the force in perpendicular direction per unit area, and serves to characterize how a given resultant force is applied on a surface

The pressure can be measured in different units some of them are atmospheres (atm), millimeters of mercury (mmHg), Bar (bar) and pascals (Pa)

By writing the pressure on any of these units we are expressing it correctly.

But the unit chosen to express the pressure in the international system is Pascal (Pa), and a pascal equals 1 Newton per square meter

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.
