Ans 5:

Rahul Jha from Delhi Public School BN, Bengaluru

Key Idea: Phenomenon of reflection is independent of medium. The deviation produced by combination of two plane mirrors is δ=2π−2θ =2π−2×π2 (θ=90o) ⇒ δ=π=180o. Hence, total deviation in incident ray is180o

When a battery is constructed such that all the positive terminal of the cells are connected to a same point and all the negative terminals of the cells are connected to another point then the grouping of cells in this manner is called the Parallel Grouping of cells. The two end terminals of the construct where all the positive and negative terminals of the cells are connected act as the corresponding terminal of the battery.

Aarushi Upadhyayula from The Cambridge International School, Bengaluru

The answer would be C. If you read the question carefully, it says, "Weaving is done by interlacing two sets of FIBRES at right angles."
