Answer: drying towels at the beach.
Explanation:
Radiation simply has to do with the energy that is gotten from a particular source and then goes through some materials. It simply means the way energy is being transmitted as waves or heat through a certain medium.
From the options given, the scenario whereby a radiation takes place is when drying towels on the beach.
Answer:
(a) 
(b) 15 hours
Explanation:
half life, T = 12 hours
No = 19 g
(a) Let N be the amount remaining after time t.
Let λ be the decay constant.
The equation of radioactivity used here is given by
(b) N = 8 gram
Substitute the values in above equation
λ = 0.0577 per hour
So, 
Take natural log on both the sides
- 0.0577 t = - 0.865
t = 15 hours

1) G. The continents are now farther apart.
2) A. P waves. They usually travel 60% faster than S waves.
3) H. A hot spot caused the Hawaiian Islands to form.
That would be a conduction.
