The helium atom is found to contain more particles than the hydrogen atom.
<h3>What is a subparticle?</h3>
An atom is composed of particles and these particles are electrons protons and neutrons. The collective name for these particles is the subatomic particles.
Now we know that the helium atom contains more sub atomic particles than the atom of hydrogen. This is because, the helium atom contains two neutrons and two protons as well as two electrons. On the other hand, the hydrogen atom contains one neutron and one proton as well as one electron.
Thus, the helium atom is found to contain more particles than the hydrogen atom.

Answer:
2.75 N
Explanation:
Given that,
Box A has a mass 21.0 kg and box B has a mass 8.0 kg.
A horizontal force of 100N is exerted on box A.
Let a be the acceleration of the system. Using second law of motion,

Now applying Newton's second law to box B. So,

So, 2.75 N is the force that box A exerts on box B.
