Open in App

Solution

Mass of Mars = $6.42 \times 10^{29} k g$
Mass of the Sun = $1.99 \times 10^{30} k g$
Total mass of Mars and Sun together = $6.42 \times 10^{29} + 1.99 \times 10^{30} = 6.42 \times 10^{29} + 19.9 \times 10^{29} = 26.32 \times 10^{29} k g$

Question 172 Mass of Mars = 6.42×1029 kg and Mass of the Sun = 1.99×1030 kg. What is the total mass ?

Mass of Mars = 6.42×1029 kg Mass of the Sun = 1.99×1030 kg Total mass of Mars and Sun together = 6.42×1029+1.99×1030=6.42×1029+19.9×1029=26.32×1029 kg

Question 172

Mass of Mars = $6.42 \times 10^{29} k g$ and Mass of the Sun = $1.99 \times 10^{30} k g$ . What is the total mass ?

Mass of Mars = $6.42 \times 10^{29} k g$
Mass of the Sun = $1.99 \times 10^{30} k g$
Total mass of Mars and Sun together = $6.42 \times 10^{29} + 1.99 \times 10^{30} = 6.42 \times 10^{29} + 19.9 \times 10^{29} = 26.32 \times 10^{29} k g$
