ANSWER FOR BRAINLIEST PLS AND FAST
Globally, the winter of 2014–15 was the warmest winter on record at that time, but it sure didn’t seem that way for most of the eastern United States. This region experienced record-low temperatures and extreme snowfall, especially in the northern and coastal areas. During this period of extreme cold and snow, it was not uncommon to see comments on social media disputing climate change. For example, some commenters took pictures of huge piles of snow and added comments such as, "This doesn’t look like global warming."

Do these commenters have a point? Should extreme snowfall over the course of a season cast doubt on the theory of global climate change? Make a scientific argument explaining why you agree or disagree with these commenters.

Answers

Answer:

I think the commenters do not have a point. one winter of extreme snowfall or cold temperatures do not effect the realism of climate change and its physical effects to the world such as (global temperature rise, warming oceans, shrinking ice sheets, glacial retreat, decreased snow cover, sea level rise, declining artic sea ice, extreme events, and ocean acidification). Just because we have one cooler summer or one colder winter does not change the facts of the situation.

Explanation:

Don't know if you still need this but this is what I wrote for my PLATO answer.

Hope this helps

These commentators don't make a valid point, though. If this was the warmest winter on record, it would be inaccurate to assert that global warming is not the cause.

What is global climate change?

Long-term changes in temperature and weather patterns are referred to as climate change.

Although these changes may be natural, human actions have been the primary cause of climate change since the 1800s.

However, these commentators don't present a convincing argument. It would be incorrect to claim that global warming is not to blame if this winter turned out to be the warmest on record.

Despite snow where they were, there is global warming overall. Just because one location had snow does not mean that all locations will also have it.

It almost seems like they just performed one experiment on one group to get their results.

Which, as we all know, is completely incorrect because it takes at least three groups to provide a measurement that is even remotely accurate.

Thus, this can be concluded regarding the given situation.

Explanation:

In a recent hockey game, one player (m=100kg) was moving at a velocity of 8 m/s when he ran into another player (m=300kg) who was at rest (v=0m/s). After the collision, the two players were stuck together (moving with the same velocity). What was their velocity after the collision?

Answers

At first you need the displacement/distance from the point he started to run to the other player
Buttttttttttt if they were at rest because the force was balanced it could be
0m/s^2
Or the other way around
25m/s^2

Their velocity after the collision was 2 m/s.

What is principle of conservation of momentum?

According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.

Given parameters:

one player (m=100kg) was moving at a velocity of 8 m/s initially.

Another player (m=300kg) who was at rest (v=0m/s) initially.

After collision they stuck together and let the velocity of them is v.

According to principle of conservation of momentum, total momentum remains conserved.

total initial momentum = total final momentum

100×8 + 300×0 = (100 + 300)v

400v = 800

v = 2.

Hence, their velocity after the collision was 2 m/s.

Processes operating in the Earth system take place on spatial scales varying from fractions of millimeters to thousands of kilometers, and on time scales that range from milliseconds to billions of years.

Examples of instantaneous - breathing; rotation of the Earth; earthquake

Examples of long term - making coal; plate tectonics

Cycles

The Earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions.

Examples of cycles: day and night; rock cycle; seasons
