Explanation:
The magnetic force is perpendicular to the velocity and the magnetic field. The direction of the magnetic force can be determined using the right-hand rule, putting the fingers of the right hand in the direction of the velocity and curl your fingers or roll them in the direction of the magnetic field. The thumb gives the direction of the magnetic force. If the charge is negative, the direction of the force is opposite to the result obtained using the right-hand rule.
The direction of a moving charge's magnetic field lines is always perpendicular to the plane created by velocity and magnetic force.
If the positive charge is moving upwards the corresponding current is also upwards, the magnetic field is towards the south.
What is magnetic force ?"Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron."
What is magnetic field ?"The magnetic field is the area around a magnet in which the effect of magnetism is felt. We use the magnetic field as a tool to describe how the magnetic force is distributed in the space around and within something magnetic in nature."

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.

Explanation:
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.

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.

If two skaters standing still push against each other, the speed of the first is the same as the speed of the second, and in the opposite direction ONLY if both people have the same mass.
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.

Contrary to popular belief, a ski jumper does not achieve a large amount of "air" when doing a jump (less than 6 feet). This is because the ramp is almost horizontal while the landing is a steep hill. If a ski jumper leaves the hill at 26 m/s in the horizontal direction then travels 240 meters down the slope, what was the vertical distance (dy) that the ski jumper fell?
Answer:
The vertical distance that the ski jumper fell is 417.45 m.
Explanation:
Given;
initial horizontal velocity of the jumper, [tex]V_x[/tex] = 26 m/s
horizontal distance of the jumper, dx = 240 m
The time of the motion is given by;
dx = Vₓt
t = dx / Vₓ
t = 240 / 26
t = 9.23 s
The vertical distance traveled by the diver is given by;
[tex]d_y = V_yt + \frac{1}{2}gt^2[/tex]
initial vertical velocity, [tex]V_y[/tex], = 0
[tex]d_y = \frac{1}{2}gt^2\\\\d_y = \frac{1}{2}(9.8)(9.23)^2\\\\d_y = 417.45 \ m[/tex]
Therefore, the vertical distance that the ski jumper fell is 417.45 m.
