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

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
