Maria’s class has learned how to drop an egg without breaking it. After 0.2 s, the kinetic energy of the falling egg is 0.5 J. If its mechanical energy is 2.3 J, what is its potential energy?
A. 1.2 J
B. 1.8 J
C. 2.8 J
D. 4.6 J
The Potential energy of the body is 11.8 Joules
The mechanical energy of the egg is given by the formula:
Mechanical energy = Potential energy + kinetic energy
Given the following parameters;
Mechanical energy = 2.3 JoulesKinetic energy = 0.5 JoulesFrom the formula:
Potential energy = ME = KE
Potential energy = 2.3 - 05
Potential energy = 1.8 Joues
Hence the potential energy of the body is 11.8 Joules

What did John Dalton contribute to the understanding of the atom?
John Dalton contribute to the understanding of the atom that all matter was composed of atoms, indivisible and indestructible building blocks.
While all atoms of an element were identical, different elements had atoms of differing sizes and mass.
What is an atom?An atom is a particle of matter that uniquely defines a chemical element.
An atom consists of a central nucleus that is usually surrounded by one or more electrons.
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
Dalton based his theory on the law of conservation of mass and the law of constant composition.
The theory states that all matter is made of atoms, which are indivisible.
(1) All matter is composed of tiny, indivisible particles, called atoms, that cannot be destroyed or created.
(2) Each element has atoms that are identical to each other in all of their properties.

Explanation:
which contains the most amount of energy a glass of water at 20C or a glass of water at 80C. EXPLAIN ANSWER
Answer:
80C
Explanation:
As a substance gets hotter, or as a substance gets closer to the state of gas, the particles in the substance move faster, become more spread out and have more energy. This is why Gas has the most energy while solids have the least. Therefore, the hotter a substance is the more energy it has.
A glass of water at 80°C will have the most amount of energy
Explanation:
The temperature is defined as the degree of hotness and coldness of the object.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature.The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.So, from this, we can conclude that glass with water at a higher temperature that is 80°C will have a higher amount of energy than a glass of water at 20°C.

Explain how balancing chemical equations relates to the law of conservation of matter.
Answer:
Normally, it explains that matter cannot be created or destroyed. It demonstrates different chemical reactions that help show the different transformations of the matter but will never destroy it or create it.
Infrared radiation A) Heat from warm objects, used to detect the location of objects Microwaves B) All the radiation humans can see, ranging from red to violet Ultraviolet light C) Used in radar and to heat food Visible light D) Given off by very hot objects, such as the sun
Answer:
Infrared radiation → A) used to detect the location of objects
Microwaves → D) Used in radar and to heat food
Ultraviolet light → C)Given off by very hot objects, such as the sun Heat from warm objects
Visible light → B) All the radiation humans can see, ranging from red to violet
Explanation:
Microwaves have magnetic waves with very long lengths, greater than that of infrared light. These waves are produced through vibrations that produce heat, as the microwave is turned on, which allows the food to be heated. These waves are also used to provide communication on some types of devices.
Infrared radiation is a type of non-ionizing radiation that has a low frequency and therefore cannot be visualized, since it is not within a visible electromagnetic spectrum, having a frequency lower than red. It can be used to detect the licalization of objects and does not pose a health risk.
Ultraviolet radiation is extremely harmful to our body. It is characterized by radiation with very small wavelengths, less than 400nm. This type of radiation can be released by the sun and ultraviolet lamps.
Visible light refers to the simplest form of electromagnetic wave and covers all the radiation that our eyes can see, allowing different colors to be seen in the objects we observe according to the reorganization of atoms and molecules.
Answer:
A=Microwaves
B=Ultraviolet light
C=Visible light
D=Infared radiation
Explanation:
A) Used in radar and to heat food
B) Given off by very hot objects, such as the sun
C) All the radiation humans can see, ranging from red to violet

Animals and Animal-like Protists share some characteristics. Tell how the organisms in these groups are the same? Why do you think scientists have placed them in different groups
Answer/Explanation:
Animals are multicellular heterotrophic organisms, meaning they cannot generate their own food, they rely on external sources of nutrition.
Protists are any eukaryotic organism that cannot be classified as an animal, plant, or fungus. The grouping is more used for convenience than anything else.
Like animals, animal-like protists can move freely and are heterotrophic. However, unlike animals, they are usually unicellular, and much simpler than animals
