Question

When wind blows, it creakes pressure on any surface it blows against. A large window has an area of 3.5m². If the wind causes a pressure of 2000pa on the window, what force acts on it ?

Answer 1

Answer:

Explanation:

Given:

Pressure: 2000 Pascals

Area : 3.5 m^2

FORCE =?

To find force we will use a formula

$Pressure = \frac{Force}{Area}$

So here we are given Pressure and Area.

Placing the values,

$2000 = \frac{Force}{3.5}$

$Force = 2000*3.5$

Force = 7000 Newton

Units are not changed because they are already in their SI units.

Some Things to Remember:-

• SI units of the following
• Force - Newton
• Area - Metre Square
• Pressure - Pascal
• If units are change such as :-
• If you get answer in Pa*m^2 while finding force remember this is also force and this is Newton's other way of writing
• Pascal can also be written as Newton per metre square,
