Answer:
gases that are not good at absorbing long wave photons of infra red.
Explanation:
border green house gases are hydrogen chloride and carbon monoxide.Border line gases like CO are weak gases but has indirect effects on global warming. This causes warming in the atmosphere.CO has a heavy mass and thus lies on border line ozone layer. These are bad absorbers unlike CO2 and steam which absorb long waves of photon of infra red well.Option B is correct

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
Answers
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.

What is the difference between an object with a constant accleration and a constant velocity?
a. There is no difference between constant velocity and constant acceleration.
b. If an object has a constant velocity it will not have an acceleration- the velocity does not change. A constant acceleration means an objects velocity will increase or decrease by the same amount in each interval of time.
c. If an object has a constant acceleration it will not have a velocity. A constant velocitty means an object will increase or decrease displacement by the same amount in each interval of time
d. If an object has a constant acceleration on a velocity vs time graph the slope of the line will = zero.

What is the relationship between speed and kinetic energy?
Answers
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.

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
Answers
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.

in 2d kinematics what does “above horizontal” mean for angles i found from vectors?
Answers
Answer:
Explanation:
140m
Explanation:
The velocity must be broken down into x (horizontal) and y (vertical) components. We can use the y component to find how high the object gets. To find vertical velocity, vy, use vy=vosinθ.
vy=(75ms)sin45o=53ms
Next we find how long it takes to reach the top of its trajectory using vf=vo+at.
0ms=53ms+(−10ms2)t
t = 5.3s
Finally, find how high the object goes with d=vot+12at2.
d=(53ms)5.3s+12(−10ms2)(5.3s)2=140m

During a spring tide, what is arrangement of the moon, the sun and the earth?.
Answers
Explanation:
Spring tides generally occur twice a month—during new and full moons, when the Earth, Sun, and Moon line up in a row. In this arrangement, the gravities of the Sun and Moon work together and have the strongest pull on Earth. This produces the largest difference between high and low tide.
Spring Tides
During full moon or new moon phases, the gravitational forces of the Sun and Moon are maximized, producing very large ranges of tidal highs and lows called spring tides

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.
Answers
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.
