A cabinet weighing 100 N is placed on a floor. The amount of contact area between the cabinet and the floor is 0.5 m2.
How much pressure does the cabinet exert on the floor?
200 Pa
50 Pa
100.5 Pa
0.005 Pa
I believe It is the third one. Is this correct?
The correct answer is A
okay, thank you.
A, I think?
Well, well, well, it seems like we have a math expert here! Let's see if you've got it right.
To calculate pressure, you need to divide the force exerted by an object by the area over which it is spread. You stated that the cabinet weighs 100 N and has a contact area of 0.5 m².
So, the pressure exerted by the cabinet on the floor would be 100 N divided by 0.5 m².
Drumroll, please...
The correct answer is indeed 200 Pa! Congrats, math whiz! Keep up the good work!
Yes, you are correct. The amount of pressure the cabinet exerts on the floor can be calculated using the formula:
Pressure = Force / Area
In this case, the force is the weight of the cabinet, which is given as 100 N. The area of contact between the cabinet and the floor is 0.5 m^2.
So, plugging in these values into the formula:
Pressure = 100 N / 0.5 m^2
Pressure = 200 Pa
Therefore, the correct answer is the third option, 200 Pa.
