Answer:
Given
- Force = 500 N
- Area = 2 m^2
- Pressure =??
As we know for pressure
Pressure = force /area
Pressure = 500 /2
Or
Pressure = 250 pascals
* The distilled or pure do not conduct electricity because the polarity of pure water is minimum, but on other hand the tap or impure water conducts electricity due to polarity.
