It would be hardness that in general best describes malleability, since malleability is a measurement of an objects ability to form and take difference shapes.
The law of reflection says that when a ray of light hits a surface, it bounces in a certain way, like a tennis ball thrown against a wall. ... Mirrors, however, don't scatter light in this way. With a smooth surface, light reflects without disturbing the incoming image.
-- The potential energy of a 12-lb bowling ball up on the shelf
doesn't have anything to do with the temperature of the ball or
the shelf.
-- The potential energy of a jar full of gas does depend on the
temperature of the gas. The warmer it is, the greater its pressure
is, and the more work it can do if you let it out through a little hole
in the jar. If it gets hot enough, it'll have enough potential energy
to blow the jar to smithereens.
Answer:
Pressure exerted on the wall is 8775 kgm/s²
Explanation:
Parameters given:
Time = 1s
Number of molecules: 5*10²³
Area: 8cm² = 8*0.0001 = 0.0008m²
Speed of molecules: 300m/s
Mass of N₂ molecule: 4.68 x 10⁻²⁶ kg
Pressure = Force/Area
Total pressure of N molecules will be:
Pressure = Force*Number of molecules/Area
Force is given as:
Force= mass*acceleration
And acceleration is:
Acceleration = velocity/time
Therefore,
Force = (mass*velocity)/time
Pressure = (mass*N*velocity)/(Area*time)
Pressure = (4.68 x 10⁻²⁶*5*10²³*300)/(0.0008*1)
Pressure = 7.02/0.0008
Pressure = 8775 kgm/s²
