Answer:
the gas that escaped from the mixture contained the missing weight
Answer:
Option B
Solution:
As per the question:
Heat produced at the rate of 10 W
The resistor R and 2R are in series.
Also, in series, same current, I' passes through each element in the circuit.
Therefore, current is constant in series.
Also,
Power,
When current, I' is constant, then
P' ∝ R
Thus

P' = 20 W
