Answer:
Change in temperature = ΔT = 26.8°C
Explanation:
Given data:
Heat absorbed = 600 j
Mass = 25.0 g
Specific heat capacity = 0.897j /g°C
Change in temperature = ΔT= ?
Solution:
Formula:
q = mcΔT
600 j = 25.0 g ×0.897 j/g°C×ΔT
600 j = 22.425 j/°C×ΔT
ΔT = 600 j /22.425 j/°C
ΔT = 26.8°C
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. The correct option is option A.

What is atom?</h3>
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
Quarks are present in protons and neutrons but not in electrons. Quarks are sub-atomic particles that have mass, but not an integer of charge.
Therefore, the correct option is option A.
