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?

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

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 :

or

Hence, this is the required solution.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
