Answers
Answer:
The answer is: A
Explanation:
Thermal energy (also called heat energy): is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
Chemical energy: is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. Usually, once chemical energy has been released from a substance, that substance is transformed into a completely new substance.
When you light the match, a chemical reaction is occurring first, and then heat will flare (thermal energy).
Let me know if anything is wrong! During my research, I noticed that mechanical energy occurs first (the option is not here), and it's related to chemical energy, so that was my decision.

it is A and D

Explain why the top of the loop cannot be the same height as (or higher than) the top of the first hill. Assume the roller coaster and its surroundings are close to a closed system. Use what you know about energy transformations and the effects of friction within a closed system to write your answer.
Passage
Examine this diagram of a roller-coaster track. The very top of the first hill (point B) is higher than the very top of the loop (point D). After the cars reach point B, this roller coaster needs no additional energy to complete its trip.
Answers
Answer:
Take a break than eat and work on it again and you will get a good score
Explanation:
The top of the loop cannot be the same height as (or higher than) the top of the first hill because of loss of energy against frictional force in the track.
What is gravitational potential energy?The energy that an item has or acquires when its location changes as a result of being in a gravitational field is known as gravitational potential energy. Gravitational potential energy can be defined as an energy that has a connection to gravitational force or gravity.
What is frictional force?The force produced by two surfaces coming into contact and sliding against one another is referred to as frictional force.
Surface roughness and the amount of force pressing them together have the biggest an impact on these forces.
The frictional force will increase and surpass the weight of the thing if an object is pushed up against the surface.
In this question, the roller-coaster starts its journey from point B and during its course of journey its potential energy at point B converts into kinetic energy and it losses some about of its kinetic energy working against frictional force. So, the height of very top of the loop (point D) should be less than that of the first hill (point B).

How do you think density plays a role in the atmosphere?
Answers
Also, gases like air are easily compressed. The weight of all the air above a given point in the atmosphere squeezes air molecules closer together. This causes the density to increase. The more air above a level (and hence the more weight of air above a level), the greater the compression.

PLEASE HELP ASAP Pay attention to what happens to the things around you as you go about your day. Describe THREE examples of Newton’s third law in action (use different ones from those described in the lesson). In your examples describe the action and the equal and opposite reaction. Must be at least three full sentences and include examples
Answers
Answer: You may want to mention the equal but opposite force of shooting a gun. (The recoil force vs. the bullet). Also, if you bounce a ball really hard, it will exert force that makes it bounce high up, and this is the same if you were to bounce the ball with little force. Also, a judge's gavel creates a sound (sound waves would be the opposite force here) after it is hit on the podium. Lastly, if you blow up a balloon without tying it, then let it go, the trapped moving particles will make the balloon fly and flail until there is no more pent-up energy inside the balloon.
Explanation: Hope this helps a little! I added an extra example just in case!
Answer:
Answer: Options A, B, and E
Explanation:
The gravitational pull on an object by another, is nothing but the force that it exerts due to its gravity. Earth has gravity, so it pulls down everything that tends to move up. Similarly, Hox and Blox have gravitational pulls on each other, due to their gravitational forces.
Where,
F = force exerted on object
G – Gravitational constant
– Mass of two objects
r – Distance between two objects
This gravitational pull varies in phase with the mass of two bodies in relation, and inversely proportionate to the distance square. Hence, the scientist could do less the distance between the bodies, or else, spend to increase the size of one of them or both the bodies.
