Answer:
Pressure of the gas = 12669 (Pa) and height of the oil is 1,24 meters
Explanation:
First, we can use the following sketch for an easy understanding, in the attached image we can see the two pressure gauges the one with mercury to the right and the other one with oil to left. We have all the information needed in the mercury pressure gauge, so we can determine the pressure inside the vessel because the fluid is a gas it will have the same pressure distributed inside the vessel (P1).
Since P1 = Pgas, we can use the same formula, but this time we need to determine the height of the column of oil in the pressure gauge.
The result is that the height of the oil column is higher than the height of the one that uses mercury, this is due to the higher density of mercury compared to oil.
Note: the information given in the units of the fluids is not correct because the density is always expressed in units of (mass /volume)
53.3 km/h is the average amount of the car trip if 80km
The Sun has<span> an "absolute magnitude" of </span>4.83 and an "apparent" magnitude of -26.8. (Which is the difference between the numbers). <span>Scientists use what is know as "</span>Absolute" Magnitude<span> to help them understand and compute how bright a star really is. The "</span>absolute" magnitude<span> of an object, such as a star, equals how bright that object would look if it were 10 parsecs, or 32.6 light years away from the Earth.</span>

Answer:
force required to push the block = 219.714 lb
Explanation:
GIVEN DATA:
weight W of block = 250 lb
coefficient of friction = 0.2
consider equilibrium condition in x direction
.........................(1)
consider equilibrium condition in Y direction
.....................(2)
SOLVING 1 and 2 equation we get N value
N = 326.36 lb
putting N value in either equation we get force required to push the block = 219.714 lb
