Which explanation is based on scientific evidence?
Answer:
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis. Such evidence is expected to be empirical evidence and interpretable in accordance with scientific method.
Explanations which are not based on mere observations or intuitions and clearly based on reported evidences and experiments are called scientific evidence.
What are scientific evidences ?Although scientists frequently utilize evidence in other ways, such as when applying ideas to real-world issues, scientific evidence is evidence that helps to either support or refute a scientific theory or hypothesis. Such proof is anticipated to be empirical and interpretable using scientific techniques.
The requirements for scientific evidence vary depending on the area of study, but they are often based on the outcomes of statistical analysis and the quality of scientific controls.
Scientific theories and laws as well as intuitional predictions have limitations to gather information from a new system. How ever scientific evidences provide more accurate data.

Explanation:
According to Newton’s second law of motion, which object will require the most force in order to change its motion?
A.
The one with the greatest mass and fastest speed
B.
The one with the least mass and greatest speed
C.
The one with the greatest mass and lowest speed
D.
The one with the least mass and slowest speed
Answer:
A. The one with the greatest mass and fastest speed
Explanation:
Newton's Second Law of Motion
F ∝ ma F ∝ m(v - u)F ∝ mv - muF ∝ ΔPSo, as per the equation the force required to be applied is directly proportional to the change in momentum.
Therefore, we can understand two things :-
More mass = more force requiredFaster speed = more force requiredThe correct option is A.

What is the relationship between speed and kinetic energy?
Explanation:
In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

Small rocky bodies that are thought to be leftover remnants from the formation of the solar system are called __________. Which term best completes the sentence
An asteroid is a type of space rock, much smaller than a planet, and moves in an elliptical orbit around the Sun.
What are asteroids?It is a smaller body that is part of the solar system and has a diameter of less than 1,000 kilometers.
Asteroids are the subject of constant study due to the proximity they maintain to Earth, despite the fact that the chances of their impacting are very low despite the fact that they have reached the planet in a very remote past.
Therefore, we can conclude that asteroids are characterized by having a very weak gravitational force, they are celestial bodies that orbit around the Sun, and that they are remnants of the matter that gave rise to the Solar System.

An eighth-grade teacher has asked you to present information to her students about how watching television can affect adolescents’ academics and behavior. What important information should you share with this audience?
Write an essay that will serve as the basis for the speech you will deliver to the students. Include important details from the selection "Television and Adolescents" to support your discussion.
As you write, remember your essay will be scored based on how well you:
develop a multi-paragraph response to the assigned topic that clearly communicates your controlling idea to the audience.
support your controlling idea with meaningful examples, information, and references for the text.
cite direct quotes and any information that has been paraphrased from the passages that you have read.
organize your essay in a clear and logical manner, including an introduction, body, and conclusion.
use well-structured sentences and language that are appropriate for your audience.
edit your work to conform to the conventions of standard American English.
Answer:
Depending on the research you find, it could vary. Explain to them that while watching TV is not an "evil" thing, it can have some effects in the youth. Tell them how it can affect the behavior with friends, family and other people whom are around them. In addition you could even as far as mentioning academic success and failure. Studies confirmed that the television media influences children behavior since early ages. It is extremely prejudicial to expose young children to television for many reasons such as: underdevelopment, optical issues, brain damage, difficulty of learning, speaking and obesity.By the time these kids become adolescents they are obese, sedentary, with heart illness and other psychological disorders. The exposure to violence, are also damaging for their mental healthy and behavior. Kids that spend great part of their time watching tv or playing video games are more susceptible to depression and mental diseases. In order to avoid these pathologies, children must be encourage to play outside and practice sports.
Watching television is very much informative on one side if we use it effectively but the prolonged use and involving more in entertainments definitely affects the academics of students and even in their behavior badly.
What are the effects of watching television on adolescents’ academics and behavior ?By the time they turn 15, the typical child born today will have spent more time watching television than in school. According to research, watching a lot of violent TV is linked to the emergence of aggressive attitudes and actions.
Television seems to encourage stereotypes about race and gender roles as well. Last but not least, television advertisements frequently prey on kids' innocence and can encourage and promote excessive materialism.
All of these negative effects can be lessened if parents limit their children's overall television consumption, support some shows while discouraging others, and constantly discuss the meaning of what they see with them.
It is challenging to assert that television programming has no impact on young people. Yet, it is similarly challenging to isolate individual shows or programming genres as the root of certain behaviors in kids without taking into account the countless alternative influences that might have an impact on their behavior.

True or False
Answer:
True!
Explanation:
F = ma (force = mass times acceleration)
The force on each skater will be the same because of Newton's 3rd law...
F (1st skater) = F (2nd skater)
ma (1st skater) = ma (2nd skater)
If the skaters have different masses, they WILL have a different acceleration. Feel free to ask questions if needed.
