From the given motions, let's determine the example which is not an example of a wave motion.
Wave motion can be defined as the transfer of energy from one point to another without the actual transfer of matter between the points.
From the given examples, the example which which we can say does not represent a wave motion is: a person dancing.
An earthquake’s energy travelling through the core of the planet is an example of wave motion since the energy travels through one point to the other.
A tsunami event occurring after an earthquake is also an example of a wave motion.
A vibrating Slinky showing crests and troughs is an example of wave motion.
While the sound of a tuba is an example of a sound wave,
Therefore, the example which does NOT represent a wave motion is a person dancing.
ANSWER:
A). A person dancing.
Answer:
A.Amorphous solid
Explanation:
There are two states used to describe solids in science; these are crystalline and amorphous (non-crystalline) solids.
Crystalline solids are solids whose constituent particles are properly arranged in a 3-dimensional structure in a crystal-like manner. They have a definite melting point and a defined shape and pattern. A common example of a crystalline solid is diamond.
Amorphous or non-crystalline solids are the opposite of the crystalline solids as there constituent particles are disorderly arranged. They do not have a defined melting point as they melt over a range of temperature.
From the above, it can be deduced that candle wax exhibits the properties of amorphous solids. give me brainliest please
Answer:
This statement is False.
Explanation:
This is because the molecules of gases are randomly traveling and they even sometimes collide with each other. So, it is true that they resist crowding but it is not always possible for the gas molecules to be as far apart as possible because of their random movements. This also makes it impossible for the gas molecules in the tank to be always at the maximum possible distance from its nearest neighbor.
However, the distance between the electrons is not due to random movements like gases. Electrons are placed at the distance from each other due to the forces of repulsion between them, as the same charged particles always repel each other. So, the dispersion of the electron on the copper ball is not due to the random distribution of electrons. However, they will be placed at a distance to each other due to the force of repulsion between them.
A light-year is a unit of distance.
The definition of a light-year is the distance light travels in one year.
Answer:
It has producer-consumer relationship with sugar-maple trees because it gets food from the trees.
Explanation:
The mourning bird is primarily a seed eater and not an insect eater. Since it is a seed eater, it will directly from the sugar-maple tree which is the producer.
In an ecosystem, the producers are plants which can trap energy directly from the sun during photosynthesis. This energy is passed on to the consumers.
Hence, the mourning bird has producer-consumer relationship with sugar-maple trees because it gets food from the trees.
