Answer:
Total pressure in atmosphere IS 4.36 atm
Explanation:
Given Data:
Depth of lake is 400 mtr
surface tension is 147 kilopascals
surface temperature 94 kelvin
Gravity = 1.35 m/s^2
specific gravity of methane(liquid) = 0.415
specific gravity of ethane(liquid) = 0.546
density of methane can be obtained as
![\rho_{methane} = 0.415\times 1000 = 415 kg/m^3](https://tex.z-dn.net/?f=%5Crho_%7Bmethane%7D%20%3D%200.415%5Ctimes%201000%20%3D%20415%20kg%2Fm%5E3)
Density of ethane can be obtained as
![\rho_{ethane} = 0.546\times 1000 = 546 kg/m^3](https://tex.z-dn.net/?f=%5Crho_%7Bethane%7D%20%3D%200.546%5Ctimes%201000%20%3D%20546%20kg%2Fm%5E3)
Total pressure in atmosphere can be obtained as
![P = surface\ tension + \rho_{max}gh](https://tex.z-dn.net/?f=P%20%3D%20surface%5C%20tension%20%2B%20%5Crho_%7Bmax%7Dgh)
![= 147 +546\times 1.35\times 400\times 10^{-3}](https://tex.z-dn.net/?f=%20%3D%20147%20%2B546%5Ctimes%201.35%5Ctimes%20400%5Ctimes%2010%5E%7B-3%7D)
= 441.84 kPa
![= 441.84\times 0.009869 atm\kPa](https://tex.z-dn.net/?f=%3D%20441.84%5Ctimes%200.009869%20atm%5CkPa)
= 4.36 atm
Answer:
The more velocity an object has the harder it is to slow it down
Explanation:
slow it down
Answer:
V = 4.63 m/s
V = 11.31 m/s
Explanation:
Given,
The distance traveled by the bus, towards north, d = 2.5 km
= 2500 m
The time taken by the trip is, t = 9 min
= 540 s
The velocity of the bus,
V = d / t
= 2500 / 540
= 4.63 m/s
At another point, the bus travels at a constant speed of v = 18 m/s
Therefore the velocity becomes
V = (4.63 + 18)/2
= 11.31 m/s
Hence, the velocity of the bus, V = 11.31 m/s
