Question

mass of earth is (5.97×10²⁴)kg and mass of the moon is (7.35×10²²)kg .what is the total mass of the two​

Answer 1

Answer:

$6.0435 \times 10 {}^{24} kg$

Step-by-step explanation:

$5.97 \times 10 {}^{24} + 7.35 \times 10 {}^{22} \\ = (5.97 \times 10 {}^{2} + 7.35) \times 10 {}^{22} \\ =(597 + 7.35) \times 10 {}^{22} \\ = 604.35 \times 10 {}^{22} \\ =6.0435 \times 10 {}^{24} kg$

Answer 2

The total mass of the Earth and Moon is 6.0435 × 10²⁴ kg

Given :

Mass of Earth is 5.97 × 10²⁴ kg and mass of the Moon is 7.35 × 10²² kg

To find :

The total mass of the Earth and Moon

Solution :

Step 1 of 2 :

Write down mass of the Earth and Moon

Here it is given that mass of Earth is 5.97 × 10²⁴ kg and mass of Moon is 7.35 × 10²² kg

Step 2 of 2 :

Find total mass of the Earth and Moon

Mass of Earth = 5.97 × 10²⁴ kg

Mass of the Moon

= 7.35 × 10²² kg

= 0.0735 × 10²⁴ kg

Hence total mass of the Earth and Moon

= Mass of Earth + Mass of Moon

= 5.97 × 10²⁴ kg + 0.0735 × 10²⁴ kg

= ( 5.97 + 0.0735 ) × 10²⁴ kg

= 6.0435 × 10²⁴ kg
