A 2210 kg 2210 kg space station orbits Earth at an altitude of 5.39 × 10 5 m. 5.39×105 m. Find the magnitude of the force with which the space station attracts Earth. The mass and mean radius of Earth are 5.98 × 10 24 kg 5.98×1024 kg and 6.37 × 10 6 m, 6.37×106 m, respectively.

18466.68 N

Explanation:

mass of satellite, m = 2210 kg

mass of earth, M = 5.98 x 10^24 kg

distance between surface of earth and the satellite, h = 5.39 x 10^5 m

radius of earth, R = 6.37 x 10^6 m

The force between the earth and the satellite is given by

F = 18466.68 N

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
