Question:-

(A) The pressure of the atmosphere is 100000 Pa Calculate the force with which the atmosphere presses on the outside of a large window 2.0m high and 1.25m wide.

(B) Explain why this force does not break the window.

(A)

As we know

Given->

Pressure-> 1atm

height-> 2 m

wide -> 1.25 m

Putting value in formula ->

(B) Because atmosphere is present on both sides of the window pane so same force is applied from both sides of the window and as we know force is a vector quantity so according to the vector sum the force got cancelled out and net force becomes zero .

That's why even in presence of this amount of force window glass donot break

which three statements are true about all alloys?
