Phases D and H are suitable. Or not?😄

Ans 13:

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 14:

Class : Class 8

Ans 15:

Class : Class 5
the correct option is b

Ans 16:

Class : Class 7
It should be B only .

Ans 17:

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 18:

Class : Class 9
Answer is B only.

Ans 19:

Class : Class 9
Bbbbbbb!

Ans 20:

Class : Class 10

Ans 21:

Class : Class 7

Ans 22:

Class : Class 9

Ans 23:

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 24:

Class : Class 7
Class:It should be A

Ans 25:

Class : Class 7
It is B. Don't go on the picture. Full and new moon are always closer to Earth.

Ans 26:

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
