Thank You Mr.Rahul

Key Idea: Phenomenon of reflection is independent of medium. The deviation produced by combination of two plane mirrors is Î´=2Ïâ2Î¸ =2Ïâ2ÃÏ2 (Î¸=90o) â Î´=Ï=180o. Hence, total deviation in incident ray is180o

Answer B is the correct answer as the question specified for the arrangement which will allow the bulb to stay lighted for the longest possible time. Option B is connected as One cell as per the circuit (all connections are in parallel), While Option D is in Series (in case of failure of one cell, the circuit will not work as the current will not pass through the cell)

According to me D is the correct answer as a wire should be connected from a terminal of a battery to the - terminal of the battery for longer stay of electric circuit, and this rule is satisfied by the circuit shown in option D.

## Ans 13:

Class : Class 6
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.
