A student weighs 600 N. The student’s shoes are in contact with the floor over a surface area of 0.012 m^2. Calculate the pressure exerted by the student on the floor.
Answers
Answer:
200000 pa
Explanation:
By definition, pressure is a force (exerted perpendicularly to some surface) divided by an area of that surface. If this force is not constant over a surface, this is the definition of an average pressure.
The Si unit for pressure is N/m, which is called Pascal (Pa) after the French scientist and philosopher.
In our case, the force is more or less uniform and is given (600 N). The area is given also: twice 0.0015 m^2, or 0.003 m^2. So the pressure is equal to 600/0.003 = 200,000 (Pa). This is about twice as much as the standard atmospheric pressure (if you ask "is this a high pressure?").
If she stood on one foot, the pressure would be twice as high.
The answer: the pressure is 200,000 Pa.
Answer:
50000P
Explanation:
Hey, that's the wrong answer! You mistook the question. This is the right one.
Pressure = Force/Area
So pressure = 600/0.012 = 50000 pascal
