The electromagnetic wave shown above is made up of vibrating Electric fields.
I assume this is why electromagnetic waves can travel through a vacuum, due to lack of matter.
as you pump more gas into the balloon, the particles become more packed, in an attempt to gain more room, the particles push on the walls of the balloon, therefore, making it expand.
Answer:
Explanation: This is a type of radioactive decay and all the radioactive process follow first order kinetics.
Half life is the time required to decompose half of the reactants. thus after every half life the reactant will decompose to half of its present value.
Now, to calculate the number of half lives, we use the formula:
where,
a = amount of reactant left after n-half lives = ?
=Let Initial amount of the reactant = 100 g
n = number of half lives
