Answer:
15 months to 24 months.....
OR, you can say 18 months to 2 years age
Second law of physics says that the applied force to a certain object is proportional to its acceleration multiplied with its mass. Written as an equation
From this the acceleration is
Thus for the same acceleration, we apply a smaller force to a low mass object.
Answer:
t = 5.94x10⁹ years.
Explanation:
The time of the explosion can be calculated using the decay equation:
<u>Where:</u>
N(t): is the quantity of the element at the present time
N(0): is the quantity of the element at the time of explosion
λ: is the decay constant
t: is the time
Knowing that the present U-235/U-238 ratio is 0.00700 and that at the time of the explosion there were equal amount of U-235 and U-238, we have:
(1)
The decay constant is equal to:
For the U-235 we have:
For the U-238 we have:
By introducing the values of and into equation (1) we have:
Therefore, the star exploded 5.94x10⁹ years ago.
I hope it helps you!
