a)10.8421 X 10^26 Kg b)10.8421 x 10^23 Kg c)10.8421 x 10^25 Kg d)1.08421 x 10^25 Kg

Answer 1

d)1.08421 x 10^25 Kg

Answer 2

d)1.08421 x 10^25 Kg

Explanation:

The combined weight of these two bodies would be the addition of the masses of the two bodies.

Given that Earth weight is 5.9736 x 10^24 Kg and Venus is 4.8685 x 10^24 Kg,

The combined weight of Earth and Venus

= 5.9736 x 10^24 Kg + 4.8685 x 10^24 Kg

=10^24(5.9736 + 4.8685)

= 10.8421 × 10^24 Kg

In standard form,

= 1.08421 × 10^25 Kg
