Explain the energy transformation that must occur for your body to participate in a physical activity, such as playing a sport.

an example is an athlete has stored chemical energy in their body like fats and sugars then the stored chemical energy turns into kinetic energy as they run down the track.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
