Question

if x is equal to 8.00 plus minus 0.04 cm and Y is equal to 0.00 + - 0.04 CM then X by Y should be expressed as​

Answer 1

Answer:

2 ± 0.3

Explanation:

if x is equal to 8.00 plus minus 0.04 cm and Y is equal to 4.00 + - 0.04 CM then X by Y should be expressed as​

Let say P = X/Y

P = 8/4 = 2

ΔP/P  = ΔX/X  + ΔY/Y

=> ΔP/2 = 0.04/8   +   0.04/4

=> ΔP/2 = (0.04 + 0.08)/8

=> ΔP =  0.12/4

=> ΔP = 0.03

X/Y  =  P ± ΔP  =  2 ± 0.3
