c

Ans 5:

correct answer is C

Ans 6:

option c

Ans 7:

Class : Class 6
its c as transparent object 1 will allow light ti pass. opaque object 2 wont allow anything to pass and will make a patch of light and the last could be anything

Ans 8:

Class : Class 9
c

Ans 9:

Ans 10:

Class : Class 9
IF [I] WILL BE TRANSPARENT ,AS WE KNOW THAT THE MATERIALS WHICH ALLOW LIGHT TO PASS THROUGH THEM ARE CALLED TRANSPARENT SO IF WE CUT OUT A SQUARE TRANSPARENT SHEET FROM A ROLL OF TRANSPARENT ,SURELY THE LIGHT PATCH WILL PASS THROUGH[II]THEN THE [II] MATERIAL SHOULD BE SOMETING WHICH CAN NOT ALLOW LIGHT TO PASS TROUGH IT IT SHOULD BE OPAQUE AND THE LAST SQUARE[III] CAN BE MADE OUT FROM ANY MATERIAL,THUS IT WILL NOT CHANGE THE ANSWER.SO WE CONCLUDE THE CORRECT ANSWER IS C

The answer can either be B or D.

Ans 5:

Class : Class 5
That answer is D as b,a and b are the best conductors of heat so the heat would pass through b,a and b faster and it is balanced.Nice question.

Ans 6:

Class : Class 4
ans is b

there is no necessity of mentioning the words: "descending order". This is contradictory to the statement: A>B>C>D. Hence the question is wrong.

Here, the correct answer is A. In (A), the incident rays are diverged after refraction, so the lens is concave and in (B), the incident rays are converged after refraction, so the lens is convex.

Here, the answer is C. Displacement is the shortest distance covered by a body. In a circular path, the distance between the initial point (Here=P) and the final point (Here=Q) will give you the displacement. Here, Shortest distance between P and Q is PO + OQ = a + a = 2a Hence, the displacement of the cyclist would be 2a.

Here, the answer is B. Since in a magnetic needle the arrow head is the North Pole, it will point towards the South Pole of the left hand side magnet and the other end of the magnetic needle (i.e; South Pole) will point towards the North Pole of the right hand side magnet.This is because like poles repel and unlike poles attract each other. Hence,the polarity of the end P of the right hand side magnet is North.
