The correct answer is a:Seawater
Answer:
The absorbed energy by the person is 
Explanation:
Given that,
Mass of person = 79 kg
Time = 6.0 s
Beta radiation = 3.0 C
Energy
We need to calculate the number of disintegration in 3 ci


We need to calculate the total energy of beta particle


We need to calculate the energy absorbed by the 79 kg of person

Put the value into the formula


Hence, The absorbed energy by the person is 
The answer is that it can involve changing the shape of matter, or changing the speed or direction of an object.
