Answer:
Breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
Explanation:
As per the question the body possesses kinetic energy but the net displacement of the particle is zero.
Before going to explain the type of motion first we have to know the basics of displacement.
The displacement is a vector quantity which has magnitude as well as direction .it is the minimum distance between two points out of all possible paths
Let us consider an example .let a body travels from point A to the point B and again comes to the back to the same point A .here the distance traveled is 2AB but the net displacement is zero.we have to apply this concept to solve this problem.
As the body possesses kinetic energy but the net displacement is zero .
This is in case of an circular motion.in circular motion the body possesses rotational kinetic energy but in every circular rotation ,the net displacement is zero.
One can take an example of oscillatory motion also.here the particle possesses vibrational kinetic energy ,but in each vibration ,the net displacement is zero.
Frozen water has move volume than water in liquid form
Answer:
b. they can be observed and measured
Explanation:
Matter is anything that has weight and occupy space. There are three states of matter namely Solid, liquid and gas.
The properties of matter are both physical and chemical in nature. Both properties can be measured and observed. Phhysical properties are anything that can be measured without changing the state of the matter. Example of physical properties includes mass, volume, length, color etc.
Chemical properties is another properties of matter. This is the ability of the states of matters to combine with other substance to form a new product for example, rusting of iron, formation of salt etc.
All this as discussed are both measurable and can be observed.
