Choices:
Star 1, Star 2, Star 3, Star 4

Star 1, Star 3, Star 2, Star 4

Star 4, Star 3, Star 2, Star 1

Star 4, Star 2, Star 3, Star 1

My answer would be: Star 4(0.3), Star 2(0.9), Star 3(5), Star 1(9)

Answer:  Star 1> Star 3 >Star 2> Star 4

Step-by-step explanation:

Since according to the given table ,

Mass of star 1 = 9 unit

Mass of star 2 = 0.9 unit

Mass of star 3 = 5 unit

Mass of star 4 = 0.3 unit.

Since mass is directly proportional to the time. ( E= m c^2)

Here, 9 unit  > 5 unit  > 0.9 unit  > 0.3 unit ( order of masses)

Therefore sequence of the stars according to their increasing order of their time.

Star 1> Star 3 >Star 2> Star 4
