Ec₁=mv₁²/2=450*26²/2=225*676=152100 J
Ec₂=mv₂²/2=450*30²/2=225*900=202500 J
ΔEc=Ec₂-Ec₁=202500-152100=50.4 kJ

Isotopes have the same number of valence electrons
Answer:
Power supply voltage can sometimes supply erratic and unsmooth voltages that fluctuate greatly. When a steady DC signal is needed and is necessary, a smoothing capacitor is the right component needed in order to smooth out the fluctuating signal to make it more steady.
