Answer:
<u>Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size.Matter can exist in several states, also called phases. The three most common states are known as solid, liquid and gas.</u><u>Matter is the Stuff Around You</u><u> </u><u>o</u><u>r</u><u> </u><u>Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).</u><u>Solid ice, water and steam are few examples of matter touched in everyday life. Subatomic particles are also considered as matter.</u>

Explanation:
A cyclic, or not, group can have lots of sets of generators with different cardinalities, a cyclic group is characterized for having a generator set with 1 single element. A generator for a cyclic group and any other element will also be a generator set.
The work needed if a force of 3N is used to move a table 25 metres is 75Nm (joules).
<h3>How to calculate work done?</h3>
Work is a measure of energy expended in moving an object. This means that no work is done if the object does not move.
Force is a physical quantity that denotes the ability to push, pull, twist or accelerate a body and which has a direction and is measured in Newtons.
Work done on an object can be calculated by multiplying the force applied to move the object by the distance the object moves as follows:
Work done = Force (N) × distance (m)
According to this question, a force of 3 Newtons is used to move a table over a distance of 25 meters. The work done on the table can be calculated as follows;
W = 3N × 25metres
W = 75Nm
Therefore, 75Nm is the work done on the table.
