SRMJEE Mock Test - 1 (Medical) - Question 4

A small telescope has an objective lens of focal length 144 cm and an eyepiece of focal length 6.0 cm. What is the magnifying power of the telescope? What is the separation between the objective and the eyepiece?

Detailed Solution for SRMJEE Mock Test - 1 (Medical) - Question 4

Focal length of the objective lens, fo = 144 cm
Focal length of the eyepiece, fe = 6.0 cm
The magnifying power of the telescope is given as:

= 24
The separation between the objective lens and the eyepiece is calculated as:
fo + fe 
= 144 + 6
= 150 cm
Hence, the magnifying power of the telescope is 24 and the separation between the objective lens and the eyepiece is 150 cm.

In erythroblastosis foetalis, why is the first pregnancy generally unaffected by Rh incompatibility?

Detailed Solution for SRMJEE Mock Test - 1 (Medical) - Question 24

During the first pregnancy, the maternal immune system is not yet sensitized to the Rh antigen, so the mother produces antibodies against Rh only after exposure to the foetal blood during delivery. This is why the first pregnancy is generally unaffected.

SRMJEE Mock Test - 1 (Medical) - Question 25

Which of the following diseases is caused by prions, and what is the primary feature of this infectious agent?

Detailed Solution for SRMJEE Mock Test - 1 (Medical) - Question 25

Prions are infectious agents composed of abnormally folded proteins. Mad cow disease (also known as Bovine Spongiform Encephalopathy) is a prion disease, where the prions cause brain damage in cattle. The prion's primary feature is its ability to induce misfolding of normal proteins in the brain, leading to neurological damage.

SRMJEE Mock Test - 1 (Medical) - Question 29

The difference between a two digit number and the number obtained by interchanging the two digits is 63. Which is the smaller of the two numbers?

Detailed Solution for SRMJEE Mock Test - 1 (Medical) - Question 29

Let the ten's digit be x and units digit be y.
Then, (10x + y) – (10y + x) = 63 ⇔ 9 (x – y) = 63 ⇔ x – y =7|
We can only find the difference of x and y, not about number.
Thus, none of the numbers can be determined.

SRMJEE Mock Test - 1 (Medical) - Question 30

Read the passage carefully and choose the best answer to each question out of four alternatives and mark your answer.
These days we hear a lot about science, but scientists, the men and women who do the work and make the discoveries, seem distant and strange to us. Science often appears to be very difficult and sometimes even magical. It is difficult of course, but we are wrong if we believe that we cannot understand it. The chief thing about the scientific method is that we get the answers to questions by making tests. The man, to take an example, who finds his bicycle tyre is flat will pump some air into it. Suppose one hour later the tyre is flat again, if the man is wise, he will first test the valve in water. If he finds air is escaping from it he will put in a new piece of valve-rubber and then pump up the tyre. All should then be well again. This man is using a simple form of scientific method.
If the man was very 'unscientific' he might say to himself that an evil spirit had caused the tyre to go flat.
The antonym of believe is -

Detailed Solution for SRMJEE Mock Test - 1 (Medical) - Question 30

Believe - Accept that (something) is true.
Reveal - Make (previously unknown or secret information) known to others.
Disbelieve - Be unable to believe.
Agree - Have same opinion about something
Deny -  State that one refuses to admit the truth.
Since, antonym means opposite.
So, from above given meanings, we can conclude that, disbelieve is the antonym of believe.
Thus, option B is the correct answer.
