A 500 g block of metal absorbs 5016 J of heat when its temperature changes
from 20.0 ⁰C to 30.0 ⁰C. Calculate the specific heat of the metal.

Specific heat of the metal = 1003.2J/kgC

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.
