2003, 2004 and 2005 question 39th which one summer or winter? :-\
And about the half life, its just the half of the real life( i.e. life/2 for one half life)
Its when the material decays, Gamma decays slowest, then comes the beta and finally alpha :)
Decays meant that it's radioactivity is reduced :)

It is accelerating hence its velocity is increasing. Thus, its KE will increase (KE = 0.5mv2)
Since it is moving upwards it is attaining a new vertical height, hence, its GPE increases.
Answer = D
