iii. Justify the poet’s allusion to Rapunzel in ‘Amanda’.

In the poem 'Amanda', the poet Robin Klein speaks about Rupanzel, a fairy who lived in a tall tower. She has bright hairs. She do not care for anything. Her life was tranquil and peaceful.  As such, Amanda also imagines a life like Rupanzel, living in a huge tower. She feel that, in the tall tower, she can do everything without being nagged from her mother. She also says that she will never let her hair down like Rupanzel. This means that, she doesn't allow anyone to come in the tower and wants to live alone and free.

Q.The resistance of a resistor is reduced to half of its initial value. Indoing so, if other parameters of the circuit remain unchanged, theheating effects in the resistor will become?

(A) two times. (B) half. (C) one-fourth. (D) four times.​ Ans:- Given Resistance is reduced to half, so resistance = R/2 Also given that, other parameters of circuits remain unchanged, For constant Current, heating effect of resister will become -  • This means that Heat is directly proportional to resistance, so when resistance is halfed, then heat effect will also become halfed For the constant Voltage, heating effect of resistor become -  • This means that Heat is indirectly proportional to resistance, so when resistance is halfed, then heat effect will also become doubled So, we found that there are 2 cases, current being constant and voltage being constant.  Note - Both cases have different answer!
