The level of mercury in an open end manometer is 20mm higher on the open
ended side. Considering the gas is at STP, what is the pressure of the gas?

106,080 newtons per meter squared

Explanation:

First you take the density of mecury multiply by the height in meters then multiply by the gravity: 13600×0.02×10= 2720

Then add the answer to the standard atmospheric presssure:

2720+ 103,360= 106,080

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
