Question

The mass of the Earth is 5.9742 x \[10^{24}\]

The mass of the sun is 333 000 times the mass of the Earth

Work out the mass of the Sun

Give your answer in the standard form correct to 3 significant figures

Can someone help me on this please?

Answer 1

Well, if the mass of the earth is \(5.9742\times10^{24}\) and the mass of the sun is 333,000 times that.. What is 333,000 times \(5.9742\times10{^24}\)

Answer 2

err 333,000 times \(5.9742\times10^{24}\)

Answer 3

Cause that's the mass of the sun.

Answer 4

i typed it into my calculator and it came up with
1.9894419 x \[10^{30}\]

Answer 5

Seems reasonable. 5.97*3.33 = 19.88, and \(10^5 \times 10^{24} =10^29\). Moving the decimal one more place would be \(1.988 \times 10^{30}\)

Answer 6

And I rounded down, so that's probably correct.
