Question

Could someone help me please

Answer 1

Jupiter has greatest mass.

Answer 2

a) If you calculaate everything, you'll find out that Jupiter has the highest mass, not only because that is what the answer syas, because it's also an exponent of a higher number (27).

b) Mercury:

4.88 * 10^3 (diameter). Radius is the half the diameter, so:

$(4,88*10^{3}) / 2$

$(4,88*1000) / 2$

$4880 / 2$

$\bf~2440$ → radius of Mercury in km.

c) Mass of Jupiter:

$1,898 *10^{27}$ = 1898000000000000000000000000000 kg

Mass of Saturn:

$5.86*10^{26}$ = 586000000000000000000000000 kg

Difference:

1898000000000000000000000000000 - 586000000000000000000000000 =                                                                     1 897 414 000 000 000 000 000 000 000 000 kg

Hope it helped,
