Answer:
i think c
Explanation:
because cars run on mechanical energy and solar powered means its by the sun which is light energy
Yessssssssssssssssssssssss
1. The mass number is protons + neutrons = mass number. In this case, we have protons + neutron = 164.The atomic number is simply the number of protons so we have 43 + neutrons = 164. Subtracting 43 from both sides we get neutrons = 121.
2. = 4
3. The number of protons in the nucleus does not equal the number of neutrons.
A=mass number:
Z=atomic number (= number of protons)
N=number of neutrons:
A=Z+N
If the number of protons in the nucleus is equal the number of neutrons , we would have an even mass number; because Z=N=x; then A=x+x=2x (this is always an even number) but 23 is an odd number, therefore the number of protons in the nucleus does not equal the number of neutrons.

of three things the photon passes through unscathed, the photon gets
absorbed by the electron of an atom and stays put, or the photon gets
absorbed and a second generation photon is generated by that electron</span>
