Explanation:
When a velocity's magnitude and direction do not alter over time, it is said to be constant.
What is meant by Constant speed?Constant speed refers to a speed that remains constant throughout the duration of the motion. Constant speed is demonstrated in our example of using cruise control while driving a car.
When a velocity's magnitude and direction do not alter over time, it is said to be constant. In other words, this occurs when an object's rate of change in location remains constant throughout time.
An object is considered to be moving at a constant speed when it covers the same distance in the same amount of time. When moving at a constant place, an object covers a certain distance in a fixed amount of time. S = dt is a formula that can be used to express the speed.

If all planets were the same distance from the sun, which would have the largest gravitational force between itself and the sun? Why?
If all planets were the same mass, which would have the lowest gravitational force between itself and the sun? Why?
Answer: Mercury
Explanation:
Looking at the general equation for gravity attached below we see that radius is indirectly proportional so as it increases the force decreases.
The masses of m1 and m2 are directly proportional so as either of them increases then the gravitational force increases.
In this example the radius and m2 are all the same so the only difference will be the mass of the other planets.
Mercury has the lowest mass of all the planets in the solar system so it will also have the lowest gravitational force between it and the sun in this example.
Why are video games so fun? Can any one explain, i'm just so confused
Answer:
I really don't know
Explanation:
Each video game is addictive for different reasons. Also, each person may find different elements of a game addictive. Although every case is unique, there are general patterns that can help explain why video games are addictive.
Video games are addictive because they help meet our basic psychological need for a sense of freedom, purpose/progress, and social connection.
Let’s take a closer look at each of these factors.
Video games offer a sense of freedom
Video games can be addictive because they offer a high degree of freedom that is unparalleled outside gaming environments. Let’s take a look at a few ways video games facilitate a sense of freedom.
Video games allow you to escape from social constraints.
From fantasy science fiction worlds to realistic combat environments, games allow a person to escape from the normal constraints of the offline world. This is especially relevant for someone struggling with social anxiety.
Offline social interaction can be challenging for individuals who find social situations anxiety-provoking, confusing, or over-stimulating. Games offer an escape from the constraints of social anxiety, providing a sense of freedom and control.
Although games serve as a short-term escape, avoiding in-person social situations comes at a long-term cost. Rather than facing one’s fears and dealing with the anxiety, games offer virtual freedom while keeping an individual dependent on the game as a form of escapism. Using games to avoid difficult emotions can lead to increased use over time, making in-person interaction even more difficult.
Video games allow you to experiment with different identities.
By experimenting with one’s personal gaming avatar, games offer the chance to try out new identities instantly, without the long-term social implications of the offline world.
This can be especially engaging for individuals who are dissatisfied with their offline identity, suffer from low self-esteem, or feel they cannot express certain aspects of their identity in their offline social context.
Identity experimentation through games can be healthy and liberating, but it can also be detrimental to developing one’s offline identity and sense of self-esteem. This is especially relevant if games serve as a form of escape or way to avoid confronting deeper self-esteem issues.
Video games offer a sense of adventure.
Games offer the infinite ability to explore new worlds. For those high in novelty-seeking, gaming environments offer a high level of exploration and experimentation without the dangers present in the offline world.
The modern world can often seem mundane, especially if you are bored and dissatisfied in your work or schooling. Gaming environments offer a way out of this monotony of everyday life and can be addictive because of the infinite possibilities they present.
Video games offer a sense of purpose
Video games can be addictive because they offer a strong sense of mission and purpose. Let’s take a closer look at how games offer a sense of purpose.
Video games facilitate a sense of progress through leveling up.
Games offer a sense of progress through their mission orientation. In addition, players gain a sense of mastery when their skills improve. This mission orientation and skill improvement are symbolized by character development, resource acquisition, leveling up to new environments, and various point systems.
This sense of progression can be especially rewarding for someone who feels like they are in a rut in their offline life. Games offer a way to meet our basic need to feel like we are progressing, even if it is virtual.
Another addictive feature common in games is their variable-ratio reward schedule. Like slot machines, games are designed with features that randomly reward players, keeping them hooked on a sense of anticipation. Loot boxes are a common form of this reward structure.
Video games with no defined end encourage infinite play.
Games with no defined endpoint encourage long-term investment. This can be addictive because the more time and energy one invests into an activity, the more difficult it is for them to simply abandon all of their efforts.
In addition, long-term play with a specific avatar builds a sense of identity investment, making it more difficult to let go.

I extracted DNA from strawberry. I had to answer: - Why did the DNA separate to the top after adding the isopropyl alcohol? - Does all of your food have DNA? Explain your reasoning. - Why is it important for scientists to be able to extract DNA? Provide two examples.
1. Isopropanol is a compound used to dissolve lipids and as a dehydrating agent. When mixed with DNA, they compete for water causing the DNA to dehydrate and separating the mixture into two phases.
2. Every living organism contains DNA. This includes plants and animals, and therefore most of the food we eat.
3. DNA contains the hereditary information of all living organisms.
For example, in humans it is important to extract DNA for the identification of diseases, their causes and possible treatments.
In food, DNA extraction can help in the production of transgenic foods.

The harmfully invasive Kudzu was introduced in the U.S. during the Philadelphia Centennial Exposition in 1876 where it was presented for sale as a green ornamental plant.
Kudzu is a green sturdy vine that is a climber. It is known for its sweet-smelling blooms. It is harmfully invasive because it poses great competition for the native plant, from grasses to large trees, and outcompetes them all by shading them and depleting them with their share of sunlight.
Ornamental plants are those that are grown for the purpose of decoration. These can be grown in gardens, fields or even indoors. Some examples of ornamental plants are: Snake Plant, String Of Pearls, Peace Lily, Chinese Money Plant, Air Plant and Water Bamboo.

Given the structure of protein, why is the energy that is released as heat during chemical reactions not useable for work in biological systems?
Energy exists in different forms, some of which are electrical, heating, chemical, luminous, among others.
Chemical energy in biological systems is based on the formation-breaking of bonds: to form a bond, energy must be expended, while when a bond is broken, energy is released.
Often, these processes require the participation of enzymes within the organisms; enzymes are proteins that decrease the activation energy of a reaction. For example, if a lot of energy is needed to break a bond, the enzyme will help to lower the energy required.
In biological systems such as humans, the energy molecule is ATP, which releases energy when a bond is broken and a phosphate group is released, leaving ADP as a product. And although it is an efficient process, the laws of thermodynamics explain that no process is 100% efficient, and therefore, some amount of energy is always released in the form of heat. Unlike chemical energy, heat energy is not stored in bonds and cannot be catalyzed by enzymes or utilized by biological systems.
