Answer:
The answer is 55.2 that is correct
Explanation:
Answer:
R = 12 ohms
Explanation:
It is given that,
Supply voltage is 12 V
Current in the circuit is 1 A
We need to find the resistance of the circuit. Ohm's law gives the relationship between current, voltage and resistance as follows :
V = IR
So, the resistance of the circuit R is 12 ohms.
<u>Answer:</u> The new volume of the gas will be 0.233L.
<u>Explanation:</u>
To calculate the new volume of the gas, we will use the equation given by Boyle's Law.
The above law states that the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(At constant temperature and number of moles)
or,
where,
are the initial pressure and volume of the gas.
are the final pressure and volume of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new volume of the gas will be 0.233L.
