Find the pressure exereted by a girl weighing 400N.standing on one heel of area 1cm square
clearly, that would be
400N/cm^2
To find the pressure exerted by the girl, we can use the formula:
Pressure = Force / Area
Given that the girl's weight is 400N and she is standing on one heel with an area of 1cm², we can substitute these values into the formula:
Pressure = 400N / 1cm²
However, before we proceed with the calculation, we need to ensure the units are consistent. The area is given in square centimeters, but it's more convenient to work with square meters for pressure calculations. So, we need to convert the area from square centimeters to square meters.
We know that 1 meter = 100 centimeters. Therefore, 1 square meter = (100cm)² = 10,000 square centimeters.
Converting the area to square meters:
Area = 1cm² = 1/10,000 m²
Substituting this value into the formula:
Pressure = 400N / (1/10,000 m²)
Simplifying:
Pressure = 400N * 10,000 m²
Pressure = 4,000,000 N/m²
Hence, the pressure exerted by the girl standing on one heel is 4,000,000 N/m² (or 4,000,000 Pascal).
