Question

Two different mass are determined as (20.5+or- 0.4)kg and (40.8+or- 0.3) kg what is the sum of the masses

Answer 1

Thus the sum of the masses is m1 + m2 = (61.3  ± 0.7) Kg

Explanation:

We are give that:

• Mass of body "m" = (20.5+or- 0.4)kg
• Mass of body "m' = (40.8+or- 0.3)
• To find: Total mass of the bodies

Solution:

m1 = (20.5+or- 0.4)kg

m2 = (40.8+or- 0.3)

m1 + m2 = ( 20.5 + 40.8 ) ± ( 0.4 + 0.3)

m1 + m2 = (61.3  ± 0.7) Kg

Thus the sum of the masses is m1 + m2 = (61.3  ± 0.7) Kg
