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

cccccccccccc

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.

Ans 13:

Class : Class 7
I agree with Aritroray the answer should be 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, let’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 – 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 – 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.
