Answer:

Explanation:

mas of proton = 1.673 x 10^-27 kg

mass of neutron = 1.675 x 10^-27 kg

mass of electron = 9.1 x 10^-31 kg

(a) the mass of proton and the mass of neutron is not exactly same.

(b) mass of proton = 1838.46 x mass of electron

mass of neutron = 1840.65 x mass of electron

(c) As proton and neutrons are more massive than the electrons, so the protons and the neutrons has the greatest contribution of mass of an atom.

(d) The greatest contribution to the chemical properties of an atom is due to the electrons.

If a hot air balloon is seen rising above the top of a hill, what is the top of the hill called? Question 2 options: delta point
timofeeve [1]

If a hot air balloon has shown rising above the top of a hill, the top of the hill is considered as a reference point.

<h2>Reference Point:</h2>

It is a point that is used to standardize a experiment. The reference point is a constant point.

In the given problem:

  • The hot air balloon is rising above the top of the hill. Here, the hill is a standard point that has a fixed (constant) height.
  • Some other reference points are the top of the Eifel Tower or a famous shop which a person use to denote a certain distance.

Therefore, "If a hot air balloon has shown rising above the top of a hill" the top of the hill is considered as a reference point.
