Answer:
A. The potential energy could be increasing like a ball thrown into the air
C. the ball could be returning to its natural resisting state
Explanation:
When an object is in motion, the energy of the object changes to and from each type. When the energy slows down then there is also changes in energy forms.
The potential energy of any object in motion like throwing a ball in the ball always increases because potential energy is directly proportional to the height of the object. When a ball is thrown up the kinetic energy converted into potential energy ad the ball reaches at maximum height which increase the potential energy of the object in motion. But after attaining the maximum height the, potential energy decreases and object falls back towards the earth.
Kinetic energy could not lost the friction because friction only prevent sliding not to prevent motion and potential energy lost it resistance while it convert into kinetic energy. So when the energy slows down it convert into potential energy converted into kinetic but kinetic energy could not lost the friction.
According to Newton's law of inertia, the ball could be returning to its natural resisting state as every object has tendency to resist changes in its velocity.
The Law of Conservation of Energy states that total energy of a system remain same but kinetic energy and potential energy do not remain same.
Hence, the correct option ar:
A. The potential energy could be increasing like a ball thrown into the air.
C. the ball could be returning to its natural resisting state.
Based on what I can make from thinking and mental observation, I think the reason being that coal isn't considered a mineral is that it is carbon based. In other words, its made from organic organisms (decayed organisms) which means that it doesn't have its own set of a defined element. While a mineral such as Iron (FE) has an atomic number of 26, electric configuration and a set atomic weight of 55.845. If there is an element feature such as this, you know for sure its Iron. Note: I got the element details because I have a periodic table chart right in front of my computer
Answer: 1. we wouldn’t be able to tilt so no day and night therefore lack of sun and night causing the earth to overheat and be too cold at some point which could kill the whole population.
2. The earth would just float around, we wouldn’t have track of time, and we could float towards the sun or too far away

Answer:
Peppered moths can be described as common insects usually ranging in size from 1.5 to 2.5 inches. Typical peppered moths are light in colour and are known as typica.
The peppered moths are normally light in colour having dark- black spots on its wings. They have a stout body with wings ranging from 45 mm to 62 mm. The peppered moths have colours which adapt them to hide from their predators.
Answer:
The correct answer will be- 21, 29, 29
Explanation:
In a DNA sequence, the nucleotide base pairs on one strand of DNA are complementary to the base pair on other strand of DNA.
According to the Chargaff rule, Adenine binds Thymine and Cytosine binds Guanosine which shows that the amount of A will equal T and the amount of G will equal C.
Therefore, when the amount of C is 21%, then the amount of G will be 21%.
To find amount of AT= 100-GC
AT= 100-42
AT= 58%
So, AT/2= 29% each
Thus, A=T= 29%
G=C=21%
