Draw a schematic and determine your thermal resistance values.
The original amount of the radioactive isotope will be 8 grams.
<h3 /><h3>What is the half-life of radioisotopes?</h3>
The amount of time required for half of a radioisotope's nuclide to decay, or change into a different species, is known as its half-life. The conversions release either beta or alpha particles, and the response can be monitored by counting the particles released.
Given that an unknown amount of a radioactive isotope with a half-life of 2.0 h was observed for 6.0 h. if the amount of the isotope remaining after 6.0 h was 24 g.
The original amount will be calculated as below:-
( 2 / 6 ) = ( Original amount / 24 )
Original amount = 4 x 2
Original amount = 8 grams
Therefore, the original amount of the radioactive isotope will be 8 grams.

Mass never just disappears. The other 4kg had to go somewhere. It could have left the scene of the fire in the form of smoke particles and hot gases.
Answer:
calcium-47
Explanation:
Just did the test. Good Luck!
Answer:
C. (100+4.9)m
Explanation:
u = 100m/s, t = 1 sec, g = 9.8m/s^2
s = ut + 1/2gt^2
s = 100×1 + 1/2×9.8×1^2 = 100+4.9
s = (100+4.9)m
