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:
Wavelength;λ = 0.0227 m
Explanation:
We are given that;
Velocity; v = 0.832 cm/s = 0.00832 m/s
f = 2.4 revs / 6.54 s = 0.367 hz
Now, wavelength is given by the formula;
Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency.
Wavelength usually is expressed in units of meters. The symbol for wavelength is λ,
so λ = v/f
λ = 0.00832/0.367 = 0.0227 m
D.) The energy needed to create work.
The answer of this question is
A.kg
The impulse is 10 kg m / s.
<u>Explanation:</u>
An impulsive force is a short duration of force. The result of the force acting for the given amount of time is that the object's speed up or slow down of mass. The impulse experienced equals the change in momentum of the object.
Given the mass m = 1.0 kg
The formula is given as,
Impulse = mass ( change in velocity)
= 1.0 ( 10 - 0)
Impulse = 10 kg m /s.
