Question

Analyze the relationship between CO2 emissions and surface temperature change between 1950 and 2000 using the data presented in the graphs.

A) increase emissions leads to an increase of CO2 in the atmosphere which definitely causes the increase in temperature

B) increase emissions leads to an increase of CO2 in the atmosphere which may be the cause of the increase in temperature

C) increase emissions leads to a decrease of CO2 in the atmosphere which may be the cause of the increase in temperature

D) increase emissions leads to an increase of CO2 in the atmosphere which may be the cause for the decrease in temperature

Answer 2

Andy sets up an experiment with the goal of determining the coefficient of static friction between a wooden block and a wooden surface. He uses a spring scale to weigh a wooden block. He then places the block on a plane and inclines it until the block begins to slide. The angle of slip is recorded. Andy repeats the experiment using a variety of materials to cover the board. He recorded the data in a table.

Andy did not distinguish between types of sandpaper. How would running two trials, one with fine sandpaper and another using coarse sandpaper, impact his results?

A) Using both types will serve to confirm the accuracy of the sandpaper results already recorded.

B) If his results are accurate, he would not expect any differences between the two sandpaper types.

C) Andy would expect the coefficient of static friction to be consistent throughout all of the trials.

D) If his results are accurate, he would expect a difference between the angle of slip, fine versus coarse.

Answer 3

what do you think

Answer 4

i dont know on this one. Its something I haven't learned.

Answer 5

Year Population
1700 600,000,000
1800 900,000,000
1900 1,500,000,000
2000 6,000,000,000

The world population is shown in this data table. Which line graph BEST displays this data?
