Answer:
U = 9253.6 J
Explanation:
It is given that,
Heat transferred in isochoric process,
Pressure in this process,
In the second step,
It is subjected to isobaric compression until its volume decreases by, (it decreases)
Heat transferred out of the gas,
In isochoric process, work done by the gas is zero as in this type volume is constant,
According to first law of thermodynamics,
.............(1)
In isochoric compression,
Let U is the total change in the internal energy of this gas. So,
U = 9253.6 J
So, the total change in the internal energy of this gas is $$9253.6 J. Hence, this is the required solution.
Explanation:
It is given that,
Velocity of particle 1, u₁ = 10 m/s
Velocity of particle 2, u₂ = 5 m/s
Let v₁ and v₂ are the final speed of both particles after the collision. Applying the conservation of momentum as :
......................(1)
For an elastic collision, the coefficient of restitution is equal to 1 as :
................(2)
On solving equation (1) and (2), we get,
So, the speeds of particle 1 and particle 2 after the collision is 5 m/s and 10 m/s respectively. Hence, this is the required solution.
