B. length = 4 cm; width = 9 cm
C. length = 6 cm; width = 7 cm
D. length = 5 cm; width = 5 cm
Initial mass of star (in Solar mass) 9 0.9 5 0.3
Which of these best shows the stars in the increasing order of the time for which they will stay on the main sequence?
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
Answer:
11= EC
Step-by-step explanation:
EC = 10 + 2 x + 19
= x + 20
So 2 x + 29 - x - 20 = 0
so x + 9 = 0
x = -9.
EC = x + 20 = -9+20 = 11.
Answer:
Step-by-step explanation:
10 + 2x + 19 = x + 20
2x - x = 20 - 10 - 19
x = -9
--------------------------------
check
10 + 2(-9) + 19 = -9 + 20
10 - 18 + 19 = -9 + 20
11 = 11
same value the answer is good
EC = 10 + 2x + 19
EC = 10 + 2(-9) + 19 (remember PEMDAS)
EC = 10 - 18 + 19
EC = 11 units
