Q:

When one enters a dark room after being in bright light one is not able to see anything clearly for a while because

A) the retina of the eye moves forward B) the retina of the eye moves backward
C) the iris is unable to dilate the pupil immediately to be able to see things D) the eye has no power of accommodation
 
Answer & Explanation Answer: C) the iris is unable to dilate the pupil immediately to be able to see things

Explanation:

The size of the pupil of the eye automatically adjusts itself  according to the intensity of light passing through it;if the intensity is more , the size is less, if less, it is more. So in our case the pupil should dilate i.e, increase in size to be able to see in the dark . This switchover takes sometime. But here the entry into the dark room is immediate . So the eye has no time to adjust itself and hence is not able to see at all for a while.

Q:

Two metallic plate of equal thickness and coefficient thermal conductivity K1 and K2 put together face to face. A common plate is constructed. What is equivalent K? 

A) K1k2/k1+k2 B) 2k1k2/k1+k2
C) K1+k2/k1k2 D) None
 
Answer & Explanation Answer: B) 2k1k2/k1+k2

Explanation:

We know that,

 

The equivalent K =  L1 + L2L1K1+L2K2

 

where L1 & L2 are plate1 & Plate2 thicknesses, K1 & K2 are coefficient thermal conductivity of plate1 & Plate2 respectively.

 

But here L1 = L2 = L (say)

 

Then K = L+L/(L/K1 + L/K2)  =  2K1K2K1+K2
