Answer:
the one that has more negative sights so the first hand on your right :)
The answer is D. 6 . This is because it is a positive slope so you can cancel out B and C and then, you count your boxes
Answer:
Change in specific internal Energy
Explanation:
Given:
- Mass of the gas, m=0.4 lb
- Initial pressure and volume are
- Final pressure and temperature are
- Heat transfer from the gas is 2.1 Btu
Since the process is isotropic we have
So the final volume of the gas is calculated.
Work in any isotropic is given by w
According to the first law of thermodynamics we have
So the Specific Internal Change is given by
So the specific Change in Internal energy is calculated.
Answer:
An object's acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant - if its direction changes. If an object's velocity is constant, however, its acceleration will be zero.
Solar it is the cheapest and widely used energy source
