Every day our earth receives 1.550x1022 j energy from the sun. if we were able to use 0.75 percent of this energy to accelerate spaceships, then how many missions would be possible in one year?

Total no. of missions in a year = 3 (approx)

Given:

Total Energy received by the Earth from the sun per day =

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 =

Number of days for the energy to last, n = = 133.34 days

Total no. of missions in a year =

Total no. of missions in a year = = 2.7

Total no. of missions in a year = 3 (approx)
