Answer:
B) The entropy is greater in the second state, with the gas on both sides of the box.
Explanation:
As we know that ,this is a irreversible process .The process leaves some effect on the surrounding or on the system itself ,is known as irreversible process.But on the other hand those process does not leave any effect on the system and surrounding is known as reversible process.
The entropy in the irreversible process always increases ,that is why the the entropy will be more when gas occupy the both boxes.
Therefore the answer is --B
Power used by the clock=1.03 W
Explanation:
resistance= 14000 ohm
voltage=120 V
The formula for the power is given by
P=(120)²/14000
P=1.03 W
Answer:
This is because white light consists of 7 colours with different angles o deviation or retraction.
Explanation:
When a narrow beam of light is refracted by a prism the light spreads into a band of colours (called the spectrum of light )
But in this case if a blue colour is observed it is due to the angle of refraction ,for instance red is refracted the least and hence is seen

➷ It would be 'when they have like charges.'
'Like charges' means the same charge. For example, two positive charged objects have like charges.
