What is the SI unit of pressure?
a) Newton
b) Ohm
c) Pascal
d) Joule
Explanation:The Pascal is the unit of pressure in the International System of Units, and is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square metre and is equivalent to 10 barye in the CGS system.
One Pascal is equal to one……applied over an area of one meter square.
a) joule work
b)Newton force
c) Ohm resistance
d) none of these
Explanation:The Pascal (Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist and mathematician Blaise Pascal. One pascal is equivalent to 1 newton (N) of force applied over an area of 1 square meter (m2).
Pressure in liquid and gases is determined by the flow of mass from a ………pressure region to a…..…..pressure region.
a) low-high
b) high-high
c) high-low
d) low-low
Pressure in the liquid…….with the depth.
a) increases
b) decreases
c)varies differently
d)remains same
Drill the three holes from the top to bottom of a long container, fill with water. Where the pressure of water will be greater?
a) top
b) middle
c) bottom
d) same
Pressure
at one depth in liquids acts……..in all direction.
a) differently
b) equally
c) variable
d) none of these
