The sample appears to have gone through 3 half-lives
1st half life: 1000 to 500 g
2nd half life: 500 to 250 g
3rd half life: 250 to 125 g
The duration of a half-life, therefore, can be inferred to be 66 ÷ (3) = 22 days.
After a 4th half life, there will be 125÷2= 62.5 g.
At this point, an additional 22 days will have passed, for a total of 88 days.
Answer is C.
Answer:
<em>W=700 Joule</em>
Explanation:
<u>Physics Work
</u>
Is the dot product of the force vector by the displacement vector

When both the force and the displacements are pointed in the same direction, the formula reduces to its scalar version

The weightlifter is applying a net force of 350 N to lift the weights a distance of 2 m, thus the net work done is

Increasing mass increases kinetic energy. This can be seen in the equation KE = 1/2 (m) (v)^2

Q=mc(t2-t1)
Q=2.06kg x specific heat of oil(191-23)
Q=2.06×c×168
Q=143.62q
The trampoline one would be for the elastic answer, the chemical one would be for the chemical answer, and the last one would be for the gravitational one :)
