Answer

The rise of liquid in one capillary is 2.2 cm and that in the other is 6.6 cm.

Explanation:

The ratio of their radii is [MP PET 1990] A) 9 : 1.

Answer :

The ratio of their radii is 3 : 1

Step-by-step Explanation :

Given : 1) Rise of liquid one capillary H1 = 2.2 cm,

2) Rise of liquid second capillary H2 = 6.6 cm

To find : Ratio of their radii = ?

Height of liquid in a capillary tube is,

H = 2T/ ρgr

(where T is surface tension of fluid)

The capillary rise is inversely proportional to the tube radius.

H α 1/R

Therefore H1 × R1 = H2 × R2

2·2 × R1 = 6·6 × R2

The ratio of radii = R1/R2 = 6.6/2.2 = 3/1

22 min left 12. MCQs (Single Correct) You are told that there are 498 wheels in the vehicles in a garage that contains both motorcycles and cars. What is the minimum cumber of vehicles in the garage? Answer Options 12A 125 3 299 300​

Answer:

125 is the answer 498÷4=124 cars 2 remaining =1bicycle =125

125 is the answer.

Step-by-step explanation:

This is a simple division problem

Dividing 498 by 4, we obtain 124.5.

the number 498 is not exactly divisible by 4, but we get a remainder of 2.

So, we can assume that there are 124 cars ( having 4 wheels) and one motorcycle( having 2 wheels).

Thus, the minimum number of vehicles = 124 + 1 = 125.
