Class : Class 7
B

Ans 2:

Class : Class 10
Phases D and H are suitable. Or not?😄

Ans 3:

Class : Class 6
The answer is (a) because when the full moon and new moon are there then the sun, earth and moon are aligned and the sun is also pulling at the sea forming big tides.

Ans 4:

Class : Class 7
It should be B only .

Ans 5:

Class : Class 10

Ans 6:

Class : Class 9
Ohh yeah,, it is A

Ans 7:

Class : Class 7
Class:It should be A

Ans 8:

Class : Class 8
It is B. Don't go on the picture. Full and new moon are always closer to Earth.

Ans 9:

Class : Class 5

Ans 10:

Class : Class 10
It is (A)

Ans 11:

Class : Class 5
how is it b, it should be a

Ans 12:

Class : Class 9
Answer is B only.

Ans 13:

Class : Class 7
B is the answer to this question

Ans 14:

Class : Class 9

Ans 15:

Class : Class 9
Even I think it is A

Ans 16:

Class : Class 9
It is a fact that the highest tides occur when the moon is full or new. In the diagram, the positions F and J are the full moons and new moons, so the correct answer should be B

Ans 17:

Class : Class 7

Ans 18:

Class : Class 9
Bbbbbbb!

Ans 19:

Class : Class 7

Ans 20:

Class : Class 9
just because we can see the whole moon during a full moon dosen't mean that on that day there will be the greatest tides as the moon dosen't cut itself into half on 1st and 3rd quarter. So, the answer must depend on the distance of the moon from the earth as the gravitational pull of the moon will have more effect when it is closer to earth and will raise bigger tides. The moon is closest to earth at phases D and H. So, clearly the answer should be A

Ans 21:

Class : Class 5
d and h are only the answers..

Ans 22:

Class : Class 10
Look at the diagram.........the faces of moon closest to the earth are D and H, hence the suitable solution is A

Ans 23:

Class : Class 5
i have done this question and they are showing b

Ans 24:

Class : Class 5
the correct option is b

if you are showing this answer wrong in Olympiad training paper and if we get the same question in examination which answer will be accepted as correct?

Ans 9:

Class : Class 7
The correct answer of this question Is option d

Ans 10:

Class : Class 9
D is answer as low pressure exists both in equator and 60° lattitude

Ans 11:

Class : Class 6
The answer is D as low pressure exists in both equator and 60 degree north and south.

Ans 12:

Class : Class 9
Both the science and geography textbooks of NCERT state that there is low pressure at 60 degree North and South also. So, the answer is D.

Ans 13:

Class : Class 9
at equator only

Ans 14:

Class : Class 10
Its D Peeps from SOF. Check ur ansers

Ans 15:

Class : Class 5
It should be D, as per the SOF Foundation Text.

Ans 16:

Class : Class 8
Answer should be D only . There is low pressure at the equator and at 60 degree north and south pole

Ans 17:

Class : Class 8
answer is D why have they written A . A is the wrong answer

Ans 18:

Class : Class 9
Please correct the answer. I think the answer should be D.

Ans 19:

Class : Class 7
It should be d if referred to any books in this world

Ans 20:

Class : Class 6
yes, the correct answer is D since there are two belts of low pressure on the earth. on the equator (due to high temperature) and between the two belts of high pressure (60 degrees North and South. ). A cannot be the correct answer.

Guys - NOT SOF but you all are wrong. I reviewed the question and saw it was written - A ball has started from a hill. Where will it be the fastest or where is the most kinetic energy so it is A. point W. If it was from which point should it start to reach the flag the fastest it would be D

Ans 8:

Class : Class 5
Well, isn't Option A the place where it slows down 'cause that's the point where the low slope starts so I thought it would be point X (Option B)
