Given a mercury barometer shows a column height of 760 mm, calculate the air pressure in Pascals. Use the density of mercury (13600 kg/m³) and gravitational acceleration (9.8 m/s²).
💡 Hint: Convert mm to meters when applying the formula.
If air pressure at sea level is approximately 101325 Pa, how does the pressure change with altitude to 3000 meters? Assume constant air density of 1.225 kg/m³.
💡 Hint: Use the same pressure formula but adjust the height for altitude.
