All of them are a source of getting energy but solar and wind energy are a more beneficial way of producing the energy we need.
Given:
The volume is V = 88 mL
Density, d = 9.77 g/mL
Because mass = volume * density, therefore the mass of the object is

Answer: The mass is 865.2 g or 0.865 kg
Answer:
c. a proton
Explanation:
A neutron is most equal in mass to a proton.
A neutron is a subatomic particle without any charges on them.
A proton is a subatomic particle with a positive charge.
- the mass of a proton and neutron are the most similar in an atom.
- the mass of a proton is 1.67 x 10⁻²⁷kg
- So also is the mass of a neutron
- the mass of an electron is 9.11 x 10⁻³¹kg
