Question : The charge has to be passed ______ to obtain maximum work from a galvanic cell.
Option 1: proportionately
Option 2: inversely
Option 3: reversibly
Option 4: uniformly
Correct Answer: reversibly
Solution : The correct answer is reversibly.
To achieve the highest work output from a galvanic cell, it is essential to pass the charge reversibly. This is because the electrical work done per second is determined by the product of the electrical potential and the total charge.
Option 1: ROL
Option 2: RUO
Option 3: VYS
Option 4: PSM
Correct Answer: ROL
Solution : Let's check each option – First option: ROL; R – 3 = O; O – 3 = L Second option: RUO; R + 3 = U; U – 6 = O Third option: VYS; V + 3 = Y; Y – 6 = S Fourth

Question : Directions: In each of the following questions, select the one that is different from the other three alternatives.
Option 1: 120 – 560
Option 2: 91 – 299
Option 3: 78 – 169
Option 4: 104 – 429
Correct Answer: 120 – 560
Solution : Let's check each option – First option: 120 – 560→120 ÷ 13 = 9.23; 560 ÷ 13 = 43.07 (Both are not the multiples of 13.) Second option: 91 – 299→91 ÷ 13 = 7; 299 ÷ 13 = 23 (Both are multiples
Question : Study the given bar graph to answer the following question. The bar graph shows the length (in thousand kilometres) of mountains, forests and rivers in different states. The length of mountains in Punjab is what percentage more than the length of rivers in Odisha?
Option 1: 400%
Option 2: 300%
Option 3: 200%
Option 4: 100%
Correct Answer: 300%
Solution : The length of the mountains in Punjab = 40 The length of rivers in Odisha = 10 Difference = 40 – 10 = 30 $\therefore$ Required percentage = $\frac{30}{10}$ × 100 = 300% Hence, the correct answer is 300%.
Question : If $a+\frac{1}{a}=3$, then the value of $a^4+\frac{1}{a^4}$ is:
Option 1: 48
Option 2: 81
Option 3: 27
Option 4: 47
Correct Answer: 47
Solution : Given, $(a + \frac{1}{a})$ = 3 Squaring both sides, we get, $(a + \frac{1}{a})^2 = (3)^2$ ⇒ $a^2 + \frac{1}{a^2} + 2 = 9$ ⇒ $a^2 + \frac{1}{a^2} = 7$ Squaring both sides, ⇒ $a^4 + \frac{1}{a^4} + 2 = 49$ $\therefore a^4 + \frac{1}{a^4}$
