Question 18

Some altimeters use the change in air pressure to measure height.

If the pressure is 101 kPa at sea level on a particular day, what will the pressure be at the top of a 750 m hill?

(Take the density of air to be constant at 1.2 kg/m³ and the gravitational field strength to be $9.8\text{ m/s}^2$ .)

$kPa8.8\text{ kPa}$

$kPa92\text{ kPa}$

$kPa110\text{ kPa}$

$kPa0.88\text{ kPa}$
