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  

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
