Question

33.ratio among linear expansion coefficient (a) area
expansion coefficient(b) and volume expansion
coefficient (y) is
(41:2:3 (2) 3:2; 1
(3) 4: 3:2 (4) all of these​

Answer 1

Answer:

Explanation:

1 2 3

Answer 2

Answer:

(1.) 1:2:3

Explanation:

coefficient of linear expansion=a

area expansion coefficient=b=2a

coefficient of volume expansion=y=3a

a:b:c=a:2a:3a=1:2:3
