Answer:

Explanation:
1. Given that,
Initial speed of a bicycle, u = 4 m/s
The final speed of a bicycle, v = 6 m/s
Time, t = 6 s
We need to find the acceleration of the bicycle. We know that, acceleration is equal to the change in speed divided by time taken. So,

So, the acceleration of the bicycle is equal to
.

The role of the gluons is to bind together the quarks that make up protons and neutrons. That is option D.
<h3>What are gluons?</h3>
Gluons are those particles found within an atom that are responsible for binding protons and neutrons together inside the nucleus of an atom.
The gluons are capable of binding the protons and neutrons together by holding together the quarks that makes up protons and neutrons.
These gluons are known to carry a color-anticolor charge which makes up the 9 types of gluons which include:
An atom is the smallest indivisible part of an element that can take part in a chemical reaction.
The proton is the positive particle of an atom which is found within the nucleus.
The neutron is the particle that is found in the nucleus of an atom which doesn't have any charge.
