In U. S. customary units, air pressure is measured in pounds per square inch. In the metric system, it is measured in Pascals, and one Pascal is equal to:. A. one pound per square foot.
b. one newton per square meter one metric ton per square mile.
c. one newton per square centimeter
d. none of these

a. are

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

i believe the answer is electric potential.
