The marbles that are 'more energetic' fall out of the tray, in the same way particles have enough energy to escape and turn into a gas.
Answer:
2,38kg
Explanation:
Mass in function of time can be found by the formula: 
, where 
is the initial mass, t is the time and k is a constant.
Given that a sample decay 1% per day, that means that after first day you have 99% of mass.
, but 
, so we have 
, then 
Now using k found we must to find 
.

As soon as the pencil stops exerting any force on the marble, the marble immediately stops exerting any force on the pencil.
