the mass of the sun is 2 x 10^30kg and the mass of earth is 6 * 10^24 kg. Approximately how many times greater is the mass of th
german

Answer:

The mass of sun is 333333.33 times greater than the mass of earth

Step-by-step explanation:

Given as :

The mass of the sun = 2\times 10^{30} kg

The mass of earth =  6\times 10^{24} kg.

Let The mass of sun is x times greater than the mass of earth

i.e The mass of sun = x × The mass of earth

or,  2\times 10^{30} kg =  6\times 10^{24} kg × The mass of earth

Or, x = \dfrac{2\times 10^{30}}{6\times 10^{24}}

Or, x = \dfrac{2\times 10^{6}}{6}

∴ x = 333333.33

So,  The mass of sun = 333333.33 × The mass of earth

Hence, The mass of sun is 333333.33 times greater than the mass of earth Answer
