Answer:
the property of liquid are
1 they can flow from one place to another if surface is slanted
2 it cannot be compressed
At the start of the 0.266 s, the object's speed was 8.26 m/s.
The question can only be talking about speed, not velocity.
Answer:
Explanation:
Given
Volume of fixed chamber ![V=1 m^3](https://tex.z-dn.net/?f=V%3D1%20m%5E3)
Initial Temperature ![T_1=300 K](https://tex.z-dn.net/?f=T_1%3D300%20K)
Final Temperature ![T_2=400 K](https://tex.z-dn.net/?f=T_2%3D400%20K)
Heat Supplied ![Q=10 J](https://tex.z-dn.net/?f=Q%3D10%20J)
From First law of thermodynamics
Change in internal energy of the system is equal to heat added minus work done by the system
![\Delta U=Q-W](https://tex.z-dn.net/?f=%5CDelta%20U%3DQ-W)
as the volume is fixed therefore work
![W=\int PdV=0](https://tex.z-dn.net/?f=W%3D%5Cint%20PdV%3D0)
thus ![\Delta U=mc_v\Delta T=Q](https://tex.z-dn.net/?f=%5CDelta%20U%3Dmc_v%5CDelta%20T%3DQ)
for mono-atomic gas is ![12.471 J/K-mol](https://tex.z-dn.net/?f=12.471%20J%2FK-mol)
![n=0.008018 mol](https://tex.z-dn.net/?f=n%3D0.008018%20mol)
and 1 mole contains ![6.022\times 10^{23} molecules](https://tex.z-dn.net/?f=6.022%5Ctimes%2010%5E%7B23%7D%20molecules)
thus No of molecules![=0.008018\times 6.022\times 10^{23}](https://tex.z-dn.net/?f=%3D0.008018%5Ctimes%206.022%5Ctimes%2010%5E%7B23%7D)
No of molecules
Answer:
11, 760 Pa.
Explanation:
By applying formula P= pgh, where P is pressure, p is density, g is gravitational acceleration (9.8 m\s2) and h is height of water level. Putting values in the formula, you can have the correct answer.
