Answer - What other sports can I try this spring?
Explanation:
Failures and successes are part of our daily lives as humans. It can be very challenging for one to accept his or her failures and bring oneself above it.
when failure occur, the best way to reverse the negative impacts it brings is to move forward and decide on what next to do.
The actions that must be taken in the processes should be quite productive enough to bring back the results one desired.
When the effects of failures prove irreversible, one would then give the mind a diversion and help his or herself think their way though the failure that was encountered.
The troposphere protect the molecules because there are higher layers on top. This makes life possible on Earth.
The quantity of substance remains after 850 years is 8.98g if the half life of radioactive radium is 1,599 years.
<h3>What is half life period? </h3>
The time taken by substance to reduce to its half of its initial concentration is called half life period.
We will use the half- life equation N(t)
N e^{(-0.693t) /t½}
Where,
N is the initial sample
t½ is the half life time period of the substance
t2 is the time in years.
N(t) is the reminder quantity after t years .
Given
N = 13g
t = 350 years
t½ = 1599 years
By substituting all the value, we get
N(t) = 13e^(0.693 × 50) / (1599)
= 13e^(- 0.368386)
= 13 × 0.691
= 8.98
Thus, we calculated that the quantity of substance remains after 850 years is 8.98g if the half life of radioactive radium is 1,599 years.
