Answer: If both gases undergo the same entropy then more heat is added to gas a because the entropy of the gas a is less than the entropy of the gas b.
Explanation:
Entropy is defined as the degree of randomness. When the temperature of the gas increases then the entropy of gas also increases.
In the given problem, Quantity a of an ideal gas is at absolute temperature t, and a second quantity b of the same gas is at absolute temperature 2t.
Heat is added to each gas, and both gases are allowed to expand isothermally. It means that the volume is constant during this process.
If both gases undergo the same entropy then more heat is added to gas a because the entropy of the gas a is less than the entropy of the gas b. If the heat is added then there will be more entropy.
Answer:
Work done by friction force= change in total Energy
so,
W= (friction force)*d= (mu*N)*(35)
so,
mu*m*g*35= 1/2*m*v^2
so,
mu= 0.5*(25.7)^2/(9.81*35)
solving it,
mu = 0.9618

Answer:
The internal resistance of the cell is 0.051 ohm.
Explanation:
Given;
emf of the battery, E = 12 V
terminal voltage of the cell, V = 8.2 V
current in the circuit, I = 75 A
let the potential drop of the cell due to internal resistance (r) = Ir
The internal resistance of the cell is calculated from the equation below;
E = V + Ir
where;
r is the internal resistance of the cell
Therefore, the internal resistance of the cell is 0.051 ohm.
