1)calculate the pressure, expressed in pascals, that the brick exerting a force of 18N, and dimensions od 9.3cm x 5.5 cm. I know that Pressure = force divided by the
To calculate the pressure exerted by the brick, you need to know the force applied and the area over which the force is distributed. Pressure is calculated by dividing the force by the area.
Given that the force exerted by the brick is 18N, we also need to determine the area. In this case, the area can be found by multiplying the length and width of the brick.
Given the dimensions of the brick as 9.3 cm x 5.5 cm, the area can be calculated as follows:
Area = length x width
Area = 9.3 cm x 5.5 cm
Area = 51.15 cm²
Since the SI unit for pressure is pascals (Pa), we need to convert the area from cm² to m². 1 m² is equal to 10,000 cm². Therefore:
Area = 51.15 cm² / 10,000
Area = 0.005115 m²
Finally, we can calculate the pressure:
Pressure = force / area
Pressure = 18N / 0.005115 m²
Pressure ≈ 3,521 Pa
Therefore, the pressure exerted by the brick is approximately 3,521 Pa.
