de broglie- electron orbits are similar to the behaviors of
heisenberg- impossible to determine the
electron or any other particle.

of an
schrodinger- developed mathematical equation to predict the probability that an
will be in a specific location.

all eukaryotic cell have mitochondria : )

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

answer

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
