Question

Mr. Nakamora wants to test the accuracy of an old balance in his classroom compared to a brand new balance that he knows is accurate. He weighs an objec on the old balance and finds it to have a mass of 15.6 grams. The same object weighs 15.9 grams on the brand-new balance. What is the percent error between the old and new balance?

Answer 2

Percentage error between the old and the new balance is 1.89 %

Step-by-step explanation:

Mr. Nakamora weighs an object on the old balance and finds it to have a mass of 15.6 grams. The same object weighs 15.9 grams on the brand-new balance.

The weight of an object in old balance, w₁ = 15.6 g

The weight of an object in new balance, w₂ = 15.9 g

Percentage error between the old and new balance is given by :

`\%\ error=(|w_1-w_2|)/(w_2)* 100`

`\%\ error=(|15.6-15.9|)/(15.9)* 100`

`\%\ error=1.886\%`

or

`\%\ error=1.89\%`

Hence, this is the required solution.
