Question

what force is required to exert a pressure of 2×10to the power 4 Pa on an area of 80cm square​

Answer 1

Answer:

$pressure \: = \frac{force}{area} \\ therefore \\ force = pressure \: \times area \\ = (2 \times {10}^{4}) \: \times 80 \\ = {2}^{1} \times {10}^{5} \times {2}^{3} \times {10}^{1} \\ = {2}^{4} \times {10}^{6} \\ = 16 \times {10}^{6} \\ = 1.6 \times {10}^{7} newton$
