if it has a diameter of 8, that means its radius is half that, or 4.
Answer:
We have 197 g of Co-60 after 18 months.
Step-by-step explanation:
We can use the decay equation.
Where:
- M(f) and M(i) are the final and initial mass respectively
- λ is the decay constant (ln(2)/t(1/2))
- t(1/2) is the half-life of Co
- t is the time at the final amount of m
<u>Therefore, we have 197 g of Co-60 after 18 months.</u>
I hope it helps you!
Answer:
THE CORRECT IS B(a and b)= p(A).P(B)
The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.
<h3>What is Electric Flux?</h3>
- A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
- According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
- A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
- Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
- The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
- A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.
