Do humans impact Earth's climate?

Answers

Answer 1

Answer: Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness.

Answer 2

Answer: Yes we do by driving cars and cutting down trees. This effects the Earth's climate.

What is BEST to say about a runner who is running at a constant velocity? A. Their acceleration is positive. B. Their acceleration is negative. C. Their acceleration is zero. D. Their acceleration cannot be determined.

Answers

The question is asking us what is BEST to say about a runner who is running at a constant velocity? A constant velocity (=speed) means that they are not getting faster or slower - they are running exactly as fast all the time. This meanst that their speed does not change, so their change of speed is equal to 0. A change of speed is called acceleration so their C. Their acceleration is zero. - C is the correct answer.

the correct answer is C.

An object falls freely from height H. if it takes one second to travel last half of total displacement find height H priop to the fall.

Answers

Answer:9.82 m

Explanation:

As we know from equation of motion

S=v*t +0.5 a t^2

Know s=H/2

a =9.82

t=1

V=0

Plugging the values

H*0.5=0+0.5*9.82*1^2

H=9.82 m

An object has an acceleration of 0 m/s². Does this mean that the object must be stationary?

Answers

No. Having '0' acceleration means not speeding up in any directions. If an object had speed before it's acceleration became '0' and if the object is not stopped the object will keep moving with constant velocity.

Zero acceleration means that the object's motion is not changing. That tells
you that the object's velocity is constant ... it's moving in a straight line at a
steady speed (which may be zero).

Why is it important for scientists to share information from their investigation?

Answers

So that such information can be analysed, scrutinised and verified with the use of experiments. Good scientists are naturally sceptical about the information that they produce. They strive to produce reliable and testable theories (using the information they have at their disposal) which can be used to find cures for diseases and also to develop the technology of the future.

Emilio's teacher told his class that a controlled experiment's results are valid only if one factor in the experiment is changed and all the other factors remain constant. Why is this statement true?Changing several different factors in an experiment takes too much time.

Changing several different factors in an experiment takes too many controls.

When only one factor is changed, you don't need to use a control.

When only one factor is changed, you can be more certain that it caused the results.

Answers

Actually, two of the statements can be argued to be true:
1)Changing several different factors in an experiment takes too many controls.

This means that for every factor that is changed you need a control which has all the other factors stable - but with many factors, this might be undoable.

2) - and this is the best answer:
When only one factor is changed, you can be more certain that it caused the results.

If this factor is the only thing that changes, you can safely assume that it caused the results!

A. When only one factor is changed, you can be more certain that it caused the results.

There are several ways to make sure the results of an investigation are valid. First, you and others can try to repeat the experiment. In addition, if it is a controlled experiment, you can make sure you have a control, only one independent variable, at least one dependent variable, and constants.

It is especially important to use only one independent variable because when only one factor is changed, you can be more certain that it caused the results. If you change multiple factors, you won't know which one was responsible for the change.
