It's important to match your exercise shoes with the type of exercise
in which you will be participating. This is to avoid muscle cramps and strains
when you are moving. It also provides room for movement for your feet as it
will move around a lot.
<span>energy provided=13.4 eV
energy released=0.7 eV
energy absorbed = 12.7eV
initial energy= -13.6eV [ground state]
final energy = -13.6+12.7 = -0.9 eV
This energy corresponds to n=4 in hydrogen atom</span>
