Answer:
Did you make sure you did it and your notifications are on
Answer:
C-People biking must follow all rules and laws applicable to a motorist, with some minor exceptions
Explanation:
People biking should ride on the right side of the right lane when safe, except to pass or make a left turn. When there is only one lane for traffic traveling in each direction and passing is permitted, the center of the street is marked with a broken yellow stripe

Answer:
n=2.32
w= -213.9 KW
Explanation:
![V_1=0.3m^3,T_1=298 K](https://tex.z-dn.net/?f=V_1%3D0.3m%5E3%2CT_1%3D298%20K)
![V_2=0.1m^3,T_1=1273 K](https://tex.z-dn.net/?f=V_2%3D0.1m%5E3%2CT_1%3D1273%20K)
Mass of air=1 kg
For polytropic process
,n is the polytropic constant.
![Tv^{n-1}=C](https://tex.z-dn.net/?f=Tv%5E%7Bn-1%7D%3DC)
![T_1v^{n-1}_1=T_2v^{n-1}_2](https://tex.z-dn.net/?f=T_1v%5E%7Bn-1%7D_1%3DT_2v%5E%7Bn-1%7D_2)
![298\times .3^{n-1}_1=1273\times .1^{n-1}_2](https://tex.z-dn.net/?f=298%5Ctimes%20.3%5E%7Bn-1%7D_1%3D1273%5Ctimes%20.1%5E%7Bn-1%7D_2)
n=2.32
Work in polytropic process given as
w=![\dfrac{P_1V_1-P_2V_2}{n-1}](https://tex.z-dn.net/?f=%5Cdfrac%7BP_1V_1-P_2V_2%7D%7Bn-1%7D)
w=![mR\dfrac{T_1-T_2}{n-1}](https://tex.z-dn.net/?f=mR%5Cdfrac%7BT_1-T_2%7D%7Bn-1%7D)
Now by putting the values
w=![1\times 0.287\dfrac{289-1273}{2.32-1}](https://tex.z-dn.net/?f=1%5Ctimes%200.287%5Cdfrac%7B289-1273%7D%7B2.32-1%7D)
w= -213.9 KW
Negative sign indicates that work is given to the system or work is done on the system.
For T_V diagram
We can easily observe that when piston cylinder reach on new position then volume reduces and temperature increases,so we can say that this is compression process.
