Answer:
The law of conservation of momentum states that, in the absence of an external force, the momentum of a system remains unchanged.
Explanation:
Answer:
18600j
Explanation:
It is given that,
Number of moles = 3
Temperature, T = 25°C = 25+273 = 298 K
The internal energy of N₂ gas is given by :
U=f\times nRTU=f×nRT
f is degrees of freedom. For diatomic gas, degree of freedom is equal to 5/2. So,
\begin{gathered}U=\dfrac{5}{2}\times 3\times 8.31\times 298\\\\U=18572.85\ J\end{gathered}
U=
2
5×3×8.31×298
U=18572.85 J
or
U = 18600 J
So, the internal energy of the gas is 18,600 J

Answer:
Part a)

Part b)

Explanation:
Part A)
As we know that time period of the motion is given as

so we have



now at the point of maximum amplitude the force equation when Normal force is about to zero is given as

so we have



Part b)
Now if the amplitude of the SHM is 6.23 cm
and now at this amplitude if object will lose the contact then in that case again we have



so now we have
