the answer in my opinion would be A
Answer: idk
Explanation: hahahaha
Answer:
32 amu is the right choice because both protons and neutrons have a mass of 1 amu. Electrons have no mass so go with the last choice
s = 25m
v = ?
a = 9.81m/s²
v² = u² + 2as
v² = 0 + 2x9.81x25
v² = 490.5
v = √490.5
= 22.15m/s
