(a) 0.94 +0.00 cm (b) 0.94 +0.01cm
(c) 0,94 +0.02 cm (d) 0.94 +0.005 cm​

Answer 1

Explanation:

36. If the length of rod A is 3.25 ± 0.01 cm and that of B is  4.19 cm then how much rod B is longer than rod A?

(a) 0.94 +0.00 cm (b) 0.94 + 0.01 cm

(c) 0,94 +0.02 cm (d) 0.94 +0.005 cm​

• Given If the length of rod A is 3.25 + 0.01 cm and that of B is 4.19
• Given length of the rod A and B
• We need to find by how much rod B is longer than rod A.
• Let the rod B be longer by m
• Therefore m = 4.19 ± 0.01 – (3.25 ± 0.01)
• So m = (4.19 – 3.25) ± (0.01 + 0.01)

So we get m = 0.94 ± 0.02 cm
