Answer: 76 N
Step-by-step explanation:
The formula for calculating pressure is expressed as
Pressure = force/area
To calculate the area, we would appply the formula for calculating the
area of a rectangle which is expressed as
Area = length x width
From the information given,
length = 0.334
width = 0.568
Pressure = 400 Pa
Recall, 1 pa = 1n/m^2
400 Pa = 400 n/m^2
Area = 0.334 x 0.568 = 0.189712 m^2
The formula for calculating force is
Force = 0.189712 x 400
Force = 76 N
