The answer D is correct. Magnetic field moves from North to South, and if you follow the direction of the compasses, you will see that this theory is true.

No guys. Human eye can't focus simultaneously on two points. To avoid parallax error , eye should be on the point of measurement to be taken.Hence given answer is correct in my view. You may comment.

## Ans 3:

Class : Class 7
No as it causes a parallax error. It should be option A. If you don't believe me then try it yourself with a scale and measuring a line segment from different eye positions. You will see that, the measurement varies slightly every time. That's why option A is correct.

it is simple that while measuring, at first you eye must be vertically above 0

## Ans 12:

Class : Class 8
I think it should be C because otherwise the zero end can shift slightly (in our viewpoint) and measurement will be wrong. So both statements a and b are correct and the answer is C.

A as image is as far behind the mirror as Object is in front of it. In this case Sachin is 3 m in front of the mirror and the object seems to be seven meters ahead. As Sachin is 3 m in front of the mirror that means object is (7-3) = 4 m behind the mirror. As image is as far behind the mirror as Object is in front of it, It means chart is 4 meters in front of the mirror. ( 4 - 3 ) = 1 m behind Sachin as Sachin is also in front of the mirror. Hope that answers your question !

Sachin is being tested for his eyesight by an optician.Now, letÃ¢Â€Â™s read the given information carefully, and find out the position of Sachin.Sachin sits 3 m in front of a plane mirror, and looks at the image of the chart of letters, which seems to be 7 m in front of him.This means the distance between the mirror and the image of the chart is (7 m Ã¢Â€Â“ 3 m = 4 m). If the image of the chart is 4 m behind the mirror, then the actual chart is placed 4 m in front of mirror.Now the chart is placed 4 m in front of the mirror, and Sachin is sitting 3 m in front of the mirror. That means the chart is placed (4 m Ã¢Â€Â“ 3 m = 1 m) behind Sachin. Hence, the right answer is Option A.

A. P could be cold-blooded animal whereas R could be warm-blooded animal. ----- Frog has backbone, lays eggs and is a cold-blooded animal. So, P can be a Frog. Humans have backbone and hair, and they are warm-blooded. So, R can be a Human Being. So, this statement is Correct.B. Q could be six-legged animal whereas R could be four-legged animal. ----- Spiders have six legs and they lay eggs. So, Q can be a Spider. Horses are four-legged animals. They have backbone and hair. So, R can be a Horse. So, this statement is Correct.C. R could breathe through lungs whereas S could breathe through spiracles. ----- Dogs breathe through lungs, they have backbone and hair. So, R could be a Dog. Cockroaches breathe through spiracles. They have backbone and lay eggs, but they have no hair. So, S can be a Cockroach. So, this statement is Incorrect.D. P could have a pair of wings whereas Q could have two pairs of wings. ----- Birds have a pair of wings. They have backbone and they lay eggs. So, P could be a Bird. Most insects have two pair of wings, and they lay eggs. So, Q could be an Insect. So, this statement is Correct.Hence, the right answer is Option C.

Letâ€™s study the given food-web carefully:The food-web is starting from P. So, P are plants (Producers). Q, T and U are eating these plants, so they are Herbivores (Primary Consumers). R are eating Q, and V are eating U, so they are Carnivores (Secondary Consumers). S are eating T as well as R
