If the absolute pressure of a gas is 550.280 kpa, its gauge pressure is a. 448.955 kpa. b. 101.325 kpa. c. 651.605 kpa. d. 277.280 kpa.

The correct answer is: Option (A) 448.955 kPa

Explanation:

The formula for the absolute pressure is given as:

Absolute-pressure = Gauge-pressure + Atmospheric-pressure

Now rearrange the above equation to find the gauge pressure:

Insert the values:

Absolute pressure = = 550.280 kPa

Atmospheric pressure = = 101.325 kPa

Gauge pressure = = ?

Hence the correct answer is: Option (A) 448.955 kPa

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
