Answer:
Explanation:
Here, we want to get the maximum load supported
From the first part of the question, we have it that:
The maximum load g, varies jointly with the width w and the height h, and inversely as the length l between the supports
Mathematically, we have that as:
where k is the proportionality constant
Now, let us get the value of k
We substitute the first set of values as follows:
Now, using this value of k, we want to get the value of g
Mathematically, we have that as:
The number of years it would take for radium to be 5 grams is 6967 years.
<h3>After how many years will only 5 grams of radium be present?</h3>
The formula that is used to represent continuous compounding or continuous decay is:
FV = A x x N
Where:
5 = 100 x e^−0.00043 x t.
In order to determine the value of t, take the following steps:
Divide both sides by 100
5/100 = e^−0.00043 x t.
Then take the In of both sides
= 6967 years
