Final answer:
To find the pressure in pascals exerted by a tooth, you convert the area to square meters and apply the formula P = F / A. With a force of 500 N over an area of 1.00 mm², the resulting pressure is 5×10¸ Pascals.
Step-by-step explanation:
When considering the amount of force you can exert with your incisors, you are dealing with a concept in physics called pressure, which relates force and area. Pressure is defined as the force exerted over a specific area, and the standard unit for this measurement is the Pascal (Pa). In this case, you're given that a force of 500 Newtons (N) is applied to an area of 1.00 mm², which must be converted into square meters (m²) for standard calculations.
First, convert 1.00 mm² into m² by using the conversion factor (1 mm = 1×10⁻³ m), so 1.00 mm² = 1.00×10⁻⁶ m². Next, apply the formula for pressure: P = F / A, where P is the pressure in Pascals, F is the force in Newtons, and A is the area in square meters.
Now, using the values provided, the calculation would be P = 500 N / 1.00×10⁻⁶ m². The result is a pressure of 5×10¸ Pascals that can be exerted by your tooth, indicating a high capability to chew through tough objects due to the large pressure exerted on a small point.
