2. calculate the pressure in pa of a brick, which weighs 40 lbs (178n) sitting flat on the
desk. the brick is about 10 cm x 24 cm. (convert centimeters to meters before
calculating the area.)

P =  741.7 Pa

Explanation:

Pressure:

It is the force applied on object per unit area. The force is applied perpendicular to the surface.

Mathematical expression:

P = F/A

P = pressure

F = force

A = area

Given data:

Weight = 178 N

Area = 10 cm × 24 cm

Pressure = ?

Solution:

Area = 10 cm × 24 cm

Area = 240 cm²

Area = 240 /10000 = 0.024 m²

Formula:

P = F/A

P = 178 N / 0.024 m²

P = 741.7 Nm⁻²

Nm⁻² = Pa

P =  741.7 Pa

answer: they produce more slow than unicellular organisms.
