as momentum is conserved, m1v=(mi m2)3/2v mi=(m1 m2)3/2 ( mutiply both sides )by rearranging and substituting 3m1=m2 the i got is 9

It should be C because we always wear woollen clothes when we go to hill stations and any other cold place . The rest all options show summer clothes but option C is a woollen cap.

Ans is c. Glucose is completely oxidised and a lot of energy is produced in aerobic respiration. In anaerobic respiration, glucose is not broken down completely and very less energy is produced.

Four different types of matter are put into the syringes as seen in the ‘Before’ diagrams. The opening of each syringe is then covered tightly and the piston is pushed as hard as possible. The results for each syringe are shown in the ‘After’ diagrams.

Which syringe is most likely to have cod liver oil in it?

A Syringe in diagram W
B Syringe in diagram X
C Syringe in diagram Y
D Syringe in diagram Z


can solid be compressed?

Ans 1:

Class : Class 4
B

Dear friends, the answer is D. There has been an error by the SOF team. Cod liver oil is a liquid, so it will flow out. As diagram Z is showing precisely that, the answer is D.

Which of the following is incorrect?

A To increase the magnetic strength, increase the number of strokes while creating magnets.
B To increase the magnetic strength, increase the number of coils around the nail.
C Magnetic force is a pulling force only.
D Magnet may lose its magnetic property when heated to a very high temperature.


all option are correct ,no option is incorrect so they should give one incorrect option.

Ans 1:

Class : Class 6
c is the answer

Ans 2:

Class : Class 6
(C) should be the ans as .IF the like pole meets each other than they will repel each other

Ans 3:

Class : Class 9
pulling force means attracting force

It is wrong because they did not ask the total number of poles 😏

UTSAV C PATEL from Podar International School SHIVAMOGAClass;It is wrong answer as they did not ask the total number of poles

Ans 4:

Class : Class 6
a

Ans 5:

Class : Class 7

Ans 6:

Class : Class 7
no it is 12 as one piece has two poles so north poles and south poles =6 6=12

Ans 7:

Class : Class 8
It is incorrect as there are six north poles and six south poles present in a magnet if it is broken into six pieces

Ans 8:

Class : Class 7
Wrong

Ans 9:

Class : Class 8
it is wrong, see 12 is the sum of north and south poles but 6 should be the answer!!

Ans 10:

Class : Class 8
IT is not correct .... because they did not ask total number of poles ....it should be A {SIX}

The answer is B

Ans 2:

Class : Class 6
see the solution the magnet gets in contact with q so it is the correct ans

Ans 3:

Class : Class 8
Yes it should be A ......because it is not possible that some of the iron bar is magnet and some is iron ....in the given figure starting of the stroke is point is Q but before that is point P which is starting of the rod so the CORRECT answer is A ..

Ans 4:

Class : Class 7
Will P be the North Pole or Q? So confusing!!🤔🤔

Ans 5:

Class : Class 7
it will be P!!!!!!!!!!!!!

Ans 6:

Class : Class 6
AS NORTH POLE INTRODUCED AT Q PART OF THE IRON ROD SO Q WILL BE NORTH POLE.

Ans 7:

Class : Class 8
B IS A WRONG ANSWER.

Ans 8:

Class : Class 7
Sorry R would be the south pole because of the reason:Q becomes the North pole, and R, where the magnet is lifted becomes the south pole.

Ans 9:

Class : Class 6
it has started magnetising from Q SO THATS WHY IT IS TELLING THAT Q WILL BE THE NORTH SEEKING POLE.

Ans 10:

Class : Class 7
The magnet first makes contact with Q, so, it is the North Pole of the magnet

Ans 11:

Class : Class 6
The correct answer is (B),Q because the magnetic contact starts on Q and not on P.

Ans 12:

Class : Class 6
A IS TH CORRECT ANSWER. In the figure they started stoking the iron piece from point P which is the starting of the iron rod. so the correct answer is A.....

Ans 13:

Class : Class 7
In the above process of magnetisation, the magnet makes its first contact with the iron rod on place R, so R would be the North pole of the magnetised iron bar.

Ans 14:

Class : Class 6
N POLE ALWAYS GIVE THAT'S WHY A

Ans 15:

Class : Class 7
The poles are end point of the magnet ,so the north pole should be P.

Ans 16:

Class : Class 6
It should be a

Ans 17:

Class : Class 7
