A body starts from rest and moves with uniform acceleration. The ratio of distances covered in 1st, 2nd, and 3rd seconds is MCQ with Answer and Explanation

Question

A body starts from rest and moves with uniform acceleration. The ratio of distances covered in 1st, 2nd, and 3rd seconds is

A. 1:4:9

B. 1:2:3

C. 1:3:5

D. 1:1:1

Answer: Option C

Solution (By JKSSB Mock Tests)

s_nth = u + a/2 (2n-1). u=0, so distances proportional to (2n-1): 1,3,5.

Correct Answer: Option A

Explanation:
COP = desired output/work input = 300/100 = 3. Typical COP > 1 for refrigerators. Memory aid: 'COP = cooling effect per work; higher = more efficient'. Thermodynamics calculation frequently tested in competitive exams.

Correct Answer: Option D

Explanation:
Fuse needs low melting point to melt at overload, high resistance to generate more heat (I²R). Tin-lead alloy suitable. Copper high melting point, not fuse material.
