By definition we have to:
Where,
Pabs: absolute pressure
Patm: atmospheric pressure
Pg: gage pressure
The atmospheric pressure is constant and its value is:
Then, by clearing gage pressure we have:
Substituting values we have:
Answer:
If the absolute pressure of a gas is 550.280 kPa, its gage pressure is:
D. 448.955 kPa
Answer: 156.02 metre.
Explanation:
Give that a certain car traveling 33.0mph skids to a stop in 39m from the point where the brakes were applied.
Let us use third equation of motion,
V^2 = U^2 + 2as
Since the car is decelerating, V = 0
And acceleration a will be negative.
U = 33 mph
S = 39 m
Substitute both into the formula
0 = 33^2 - 2 × a × 39
0 = 1089 - 78a
78a = 1089
a = 1089 / 78
a = 13.96 m/h^2
If we assume that the car decelerate at the same rate.
the distance the car will stop had it been going 66.0mph will be achieved by using the same formula
V^2 = U^2 + 2as
0 = 66^2 - 2 × 13.96 × S
4356 = 27.92S
S = 4356 / 27.92
S = 156.02 m
Therefore, the car would stop at
156.02 m
This is amazing. When you read the quest ion, you wouldn't think there's enough information there to find an answer. But there is !
-- When the block is sliding along the flat surface, its kinetic energy is (1/2)(Mass·v²).
-- When it's 2.5m up the ramp and stops, its potential energy is (2.5m)·(Mass·g).
-- If there's no friction anywhere, these energies are equal.
(1/2)(Mass·v²) = (2.5m)·(Mass·g)
(v²/2) = (2.5m) · g
v² = 5m · g
v² = 49 m²/s²
<em>v = 7 m/s </em>(B)
Eukaryotic cells contain membrane-bound organelles, including a nucleus.Prokaryotic cells<span> do not contain a nucleus or any other membrane-bound organelle. i think thats the answer but if im wrong im sorry</span>
