During which radioactive decay process does a neutron change into a proton? A. Alpha decay
B. Gamma decay
C. Beta decay (positron)
D. Beta decay (electron)

QUESTIONS:- During which radioactive decay process does a neutron change into a proton?

A. Alpha decay

B. Gamma decay

C. Beta decay (positron)

D. Beta decay (electron)

ANSWER:-

D. Beta decay (electron)

Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.

In beta minus (β−) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

nah.   i'm just sleepy.
