Question

The masses of four objects were measured during a physics experiment. The first and the last each had a mass of 41.918 g. The second and the third objects each had a mass of 24.83 g. Find the total mass of the four objects. Write your answer in scientific notation.

Answer 1

For this case, the first thing we must do is add all the masses.
 We have then:
 M = (41,918) + (41,918) + (24.83) + (24.83)
 M = 133,496
 We now write the answer in scientific notation:
 M = 1.33496 * 10 ^ 2 grams
 Answer:
 The total mass of the four objects is:
 M = 1.33496 * 10 ^ 2 grams

Answer 2

Answer:

133.496 gram

Step-by-step explanation:

There are four object

The first object has mass 41.918 g

The second object has mass 24.83 g

The third object has mass 24.83 g

The fourth object has mass 41.918 g

∴ Total Mass of four object = ( Mass of 1st object) + ( Mass of 2nd object) + ( Mass of 3rd object) + ( Mass of 4th object)

= 41.918 g + 24.83 g + 24.83 g + 41.918 g

= 133.496 g

Hence, the total mass of four objects is 133.496 g
