Question

Mass of Mars is 6.42 × 10^29 kg and mass of the Sun is 1.99 × 10^30 kg. What is the total mass?

Answer 1

mass of Mars = 6.42 * 10^29
mass of sun = 1.99 * 10^30 = 19.9 * 10^29
so,
(6.42 + 19.9) * 10^29
= 26.32 * 10^29
=. 2.632 * 10^30

Answer 2

Answer:

The total mass is $2.632\times 10^{30}$

Step-by-step explanation:

Given : Mass of Mars $6.42\times 10^{29}$ kg and Sun is $1.99\times 10^{30}$ kg.

To find : The total mass?

Solution :

Mass of the Mars $M_m=6.42\times 10^{29}$

Mass of the Sun $M_s=1.99\times 10^{30}$

Total mass is  

$T=M_m+M_s$

$T=6.42\times 10^{29}+1.99\times 10^{30}$

$T=(6.42+1.99\times 10)\times 10^{29}$

$T=(6.42+19.9)\times 10^{29}$

$T=26.32\times 10^{29}$

$T=2.632\times 10^{30}$

Therefore, The total mass is $2.632\times 10^{30}$
