If a metal block applies a force of 20 N on an area of 5 cm2. Find the pressure being applied by the block on the area of _____ ?
Answer: 4 Ncm^-2
Explanation
To find the pressure, you need to divide the force (20 N) by the area (5 cm^2).
Since 1 cm^2 = 0.0001 m^2, the area in square meters is:
5 cm^2 x (0.0001 m^2/cm^2) = 0.0005 m^2
Now, you can calculate the pressure:
Pressure = Force / Area = 20 N / 0.0005 m^2 = 40,000 N/m^2
Since 1 N/m^2 = 1 Pascal (Pa), you can convert the pressure to N/cm^2:
40,000 N/m^2 x (1 m^2 / 100 cm^2) = 4 N/cm^2
