what is the pressure exerted on a 100 cm2 plate by a weight of 200 n resting on the plate? 0 a) 20 mpa o b) 20,000 kpa c) 2 pa ○ d) .05 pa 0 e) 20 kpa save

The answer is E) 20kPa  

Explanation:

Here we use the definition of Pressure: Pressure is a physical quantity that measures the projection of force in the perpendicular direction per unit area. In this case, wehave a 200N Force over a 100cm^2 Area

In order to have the pressure in international units we need to convert those cm^2 to m^2 this way:

We know 100cm is equal to 1m

In this case, the area will be equal to 0,01m^2

With this information we use the Pressure equation, which based on the definition will be:

Solving:

Then P is the same as 20kPa
