The pressure exerted by a liquid at a depth of 2.5m is 36,750 Pa. What is the density of the liquid, to the nearest kg/m³?
A pool containing a liquid with a density of 1,000 kg/m³ at the surface of an unknown planet produces a pressure of 8,400 Pa at a depth of 2.4 m. What is the acceleration due to gravity (g)at the surface of the planet?

Explanation:

Given

The pressure exerted at a depth of is  

Also, the gauge pressure is given by

Putting values

(b)

The density of the liquid is

depth

Pressure

We can write

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
