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.

Answer:
the work done by a person is 1,732 J
Explanation:
The computation of the work done by a person is as follows;
The following information is given
Force = 200.N
Distance = 10.0 meters
Angle = 30 degrees
based on the above information
Work done is
Work done is
= (200) (cos 30 degrees) (10.0 meters)
= 1,732 J
hence, the work done by a person is 1,732 J
The same is considered and relevant
Melting and pressure.
Weathering and erosion affect any surface rock and make sedimentary rocks, heat and pressure make metamorphic rocks, and melting and cooling make igneous rocks. Melting and pressure is not a step.
