Answer:
T₂ = 111.57 °C
Explanation:
Given that
Initial pressure P₁ = 9.8 atm
T₁ = 32°C = 273 + 32 =305 K
The final pressure P₂ = 11.2 atm
Lets take the final temperature = T₂
We know that ,the ideal gas equation
If the volume of the gas is constant ,then we can say that
Now by putting the values in the above equation ,we get
T₂ = 384.57 - 273 °C
T₂ = 111.57 °C
Answer:
Final speed of both the cars, V = 3.28 km/h
Explanation:
It is given that,
Mass of the railway car,
Initial speed of the railway car,
Mass of another car,
Initial speed of another car,
To find,
The speed of the coupled cars after the collision.
Solution,
It is a case of inelastic collision in which the linear momentum before and after the collision remains same. Let V is the coupled velocity of both of the cars. So,
V = 1.011 m/s
or
V = 3.28 km/h
So, the speed of the coupled cars after the collision is 3.28 km/h. Hence, this is the required solution.
