Energy order is nuclear --> thermal --> mechanical --> electrical.
What is thermal energy?The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is performed in the process.
Mechanical energy, also known as kinetic energy or potential energy, is the energy that an object possesses when it is in motion or the energy that an object stores due to its position. Renewable energy is also fueled by mechanical energy.

What are examples of pollution that can be caused by agriculture?
A) mercury and cyanide tailings
B) animal waste and pesticide
C) salt and soil sediments
D) gasoline and oil seeping into groundwater
Answers
Examples of pollution that can be caused by agriculture are animal waste and pesticides. The correct option is B.
What is agricultural pollution?Agriculture can be a significant source of pollution, particularly from the use of chemicals such as fertilizers and pesticides, and the disposal of animal waste.
Animal waste can pollute waterways with excess nutrients, such as nitrogen and phosphorus, which can lead to harmful algal blooms and oxygen depletion in aquatic ecosystems. Additionally, animal waste can contain pathogens and bacteria that can contaminate water sources and pose a risk to public health.
Pesticides can also contaminate waterways and soil, which can have negative impacts on ecosystems and human health. Pesticide residues can accumulate in crops and animal products, leading to long-term exposure in humans and animals.
Other examples of agricultural pollution include soil erosion, which can lead to the deposition of sediments in waterways, and the use of excessive salt in irrigation practices, which can lead to soil salinization and reduce crop productivity.
Therefore, Animal waste and pesticides are examples of pollution that can be caused by agriculture.

Answer:
98% sure the answer is A, as coal, when burning, releases thermal and light energy through the fire.
Explanation:

Help me answer these, please. I GIVE CROWNS!! PLEASE!!
Answers
Answer: 1- A diagram showing the forces acting on the object.
2- The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector.
3- A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.
4- I don’t know
5- When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces
6- By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.
7- If the forces on an object are unbalanced, this is what happens: a stationary object starts to move in the direction of the resultant force.
8- Imbalance or unequal force
9- The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.
10- net force is the vector sum of all the forces that act upon an object.
RESTATE THESE
Explanation:
RESTATE!!!!
2. They tell us about the direction of the force and the magnitude of the force relative to the other forces acting.
3. Larger vector arrows demonstrate a larger magnitude of a certain quantity. Vice versa.
4. In which direction are all of the forces in the diagram?
5. It means that there is no net force on the object - the forces sum up to zero. Forces are balanced if they are equivalent and in opposite directions.
6. Unbalanced forces ALWAYS CAUSE ACCELERATION (speeding up / slowing down). If an unbalanced/net force acts on an object, that object will ALWAYS accelerate in that direction for as long as the force is applied.
7. It means that there IS a net force acting on the object, aka the sum of the forces is greater than zero.
8. Net forces. Symbolized by Fnet or Greek letter Sigma before the F.
9. Absolutely no CHANGE IN motion. This is Newton’s First Law of Motion - basically all objects continue in their state of motion unless acted on by an unbalanced force. Note if an object is already moving and balanced forces act on it, it will continue moving. No change in motion.
10. It is the vector sum of the forces acting on an object in a certain direction.

Objects that are denser than water will sink in water. Question 1 options: True False
Answers
For example, a very dense metal will sink to the bottom while something like wood will float on the surface. The wood is less dense compared to the water, which is why it floats. Density is the measure of how much stuff you can pack in a certain volume. The higher the density, the more stuff per volume. Think of it like packing a suitcase. If there's barely anything in there, then we can say its density is low. The more stuff crammed in the suitcase will increase the density (and therefore the weight), while keeping the volume the same.

A. weights of the objects
B. distance between the objects
C. acceleration of the objects
D. masses of the objects
Answers
explanation:
because as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.

Use the information and model to answer the following question.
Echippus is an early ancestor to modern horses that lived 40 million years ago. The organism had a short neck, a short tail and feet with four toes. After ten million years, the tail and neck became longer and one of the toes disappeared as evidenced by the fossil of Mesohippus. Evolution of these organisms continued for 20 million years up to the present day causing the organisms to have longer necks and one solid hoof.
Answers
Answer:
D
Explanation:
The fossil record shows that the mammals gradually evolved so that their toes became one large hoof so this variation must have been more useful for survival than many toes. The correct option is 1.
What is fossil record?Paleontologists, archaeologists, and geologists use the fossil record to place important events and species in the correct geologic era.
It is based on the Law of Superposition, which states that the bottom layers in undisturbed rock sequences are older than the top layers.
The neck and toes of early horse ancestors evolved in such a way that the neck and tail became longer and one of the toes disappeared over time. The fossil record demonstrates this, as Echippus had a short neck, a short tail, and four-toed feet.
The fossil record shows that mammals gradually evolved their toes into one large hoof, implying that this variation was more useful for survival than many toes.
Thus, the correct option is 1.

Astronomers use different types of telescopes to observe different parts of the
electromagnetic spectrum. This allows astronomers to study objects in space. Some
electromagnetic waves are blocked by Earth's atmosphere, making it difficult for
astronomers to focus the energy into a viewable image. Instead of actually viewing
the energy, astronomers have learned to view the interactions of the energy with
the atmosphere. These faint interactions with the atmosphere allow them to study
highly energetic objects such as pulsars and black holes.
