Answer:
Total no. of missions in a year = 3 (approx)
Given:
Total Energy received by the Earth from the sun per day = [tex]1.550\times 10^{22 J[/tex]
Percent Energy used to accelerate spaceship = 0.75%
Solution:
Now, to calculate the number of launches possible in a year, we first calculate the number of days this energy would last and it is given by:
Number of days for the energy to last, n = [tex]\frac{Total enenrgy}{0.75%\times Total Energy}[/tex]
Number of days for the energy to last, n = [tex]\frac{1.550\times 10^{22}}{0.75\times 10^{- 2}\times 1.550\times 10^{22}}[/tex] = 133.34 days
Total no. of missions in a year = [tex]\frac{No. of days in a year}{n}[/tex]
Total no. of missions in a year = [tex]\frac{365}{133.34}[/tex] = 2.7
Total no. of missions in a year = 3 (approx)
