Answer: 
Explanation:
If we have an initial amount of a radioactive material or substance, which is 
, and we also are told this amount decays 
each year, this means each year 
of the substance remains:
<u />
<u>To understand it better:</u>
Year 1: 
Year 2: 
Year 3: 
and so on until year 
:
Year t: 
Therefore, the function tha best describes this radiation decay situation is:
Answer:
It may be combine?
Do you have multiple choice i can see?
Explanation:
The amount of work done by Pravat if he exerts a force of 30 N to lift a bag of groceries 0.5m is 15J.
<h3>WORK DONE:</h3>
The work done by a body can be calculated by multiplying the force exerted by the distance moved. That is;
Work done = force (F) × distance (m)
According to this question, Pravat exerts a force of 30N to lift a bag of groceries 0.5 m. The work done is calculated as follows:
Work done = 30N × 0.5m
Work done = 15J
Therefore, the amount of work done by Pravat if he exerts a force of 30 N to lift a bag of groceries 0.5m is 15J.

Particles transfer energy physically from one to the other either horizontally in a longitudinal wave, vertically in a transverse wave, or in circles in a surface wave. Waves can also be electromagnetic, which are always transverse and do not require a medium to propagate, like light waves traveling through space.
The answer that best fits the blank provided is the term INDUCTION. What is being described above is what we call the Principle of Induction. This is when a coil is being used in order to create and increase electric potential difference. This is when battery voltage comes in.
