Answer:
-10 m/s²
Explanation:
Average acceleration is change in velocity over change in time.
a = (v − v₀) / (t − t₀)
a = (0 m/s − 20 m/s) / (2 s − 0 s)
a = -10 m/s²
Radioactive "decay" means particles and stuff shoot OUT of a nucleus.
After that happens, there's less stuff in the nucleus than there was before.
So the new mass number is always less than the original mass number.

The work done by the electric field is equal to the loss of electric potential energy of the proton in moving from its initial location to its final location:
where
is the proton charge,
and
are the voltages in the final and initial locations. Substituting, we get
Answer:
Here, "v" is the velocity of electron and "V" is the potential.
