Answer:
The initial and final temperatures of the gas is 300 K and 600 K.
Explanation:
Given that,
Entropy of the gas = 14.41 J/K
Absorb gas = 6236 J
We know that,
At constant pressure,
Put the value into the formula
...(I)
We need to calculate the initial and final temperatures of the gas
Using formula of energy
Put the value into the formula
Put the value of T₂
Put the value of T₁ in equation (I)
Hence, The initial and final temperatures of the gas is 300 K and 600 K.
Answer:
The value is
Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here is the angular velocity which is mathematically represented as
substituting for T(i.e the period of the moon ) we have
=>
From the question r(which is the radius of the orbit ) is evaluated as
substitute for R and
H
=>
So
