At the bottom of a mine shaft, the air pressure is 138,000 Pa. How deep is
the mine?
(Unit = m)
1 atm = 101300 Pa
Pair = 1.29 kg/m3

Abeam of electrons with of wavelength of 7.5 x 10-6 m is incident on a pair of narrow rectangular slits separated by 0.75 mm. the resulting interference pattern is projected onto a screen 10.0 m from the slits. what is the separation of the interference maxima in the resulting interference pattern?

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

If y gets smaller as x gets bigger and y have an relationship?
