Answer:
The work done on the gas = 2PV
Explanation:
In this question, we need to apply the basic gas laws to determine the word done.
For this question, we need to draw a PV diagram (a pressure-volume diagram), which I have made and attached in the attachment. So please refer to that attachment. I will be using this diagram to solve for the work done on the gas.
So, Please refer to the attachment number 1. where x -axis is of volume and y-axis is of pressure.
As we know that, the work done on the gas is equal to the area under the curve.
W = Area of the triangle
W = 0.5 x ( base) x ( height)
W = 0.5 x (BC) x (AC)
W = 0.5 x (3V-V) x (3P-P)
W = 2PV
Hence, the work done on the gas = 2PV
Explanation:
v = wavelength x frequency
330 = 5 . 10-² m x f
f = 6600 Hz
the frequency that human can hear is about 20 Hz - 20000 Hz
so human can hear the note.
color of the indicator in asolution of ph 3 will be yellow.
Answer:
2.56 parsec
Explanation:
Parallax angle is the angle subtended by Earth over a gap of 6 months in its orbital path around the Sun with respect to a star. It can be used to measure the distance to the star.
Given: p = 0.39"
Substitute the value:
parsec
Firstly, when we say precision, this means the level of detail of a number. On the other hand, significance means that how precise a number is written and accuracy is defined as how close the number is to an actual value. Significant figures represent the precision of a measurement and not its accuracy because when a measurement has a larger number of significant figures, it has a greater reproducibility <span>or precision because it has a smaller source of error in the estimated digit. Hope this answer helps.</span>
