A testing machine uses a flat plate to compress a foam sample. The plate pushes at right angles to the sample. During a second test, the force from the plate increases from 90 N to 150 N and the contact area doubles. How does the pressure during the second test compare with the pressure during the first test?
The pressure during the second test is five-sixths of the pressure during the first test
The pressure during the second test is ten-thirds of the pressure during the first test
The pressure during the second test is five-thirds of the pressure during the first test
The pressure during the second test is three-fifths of the pressure during the first test
