HELP WILL MARK U BRAINLESIST A 20 pound barbell is brought from earth to the International Space Station(ISS). How does this trip affect the
gravitational force between the two ends of the barbell? Assume the distance between the barbell end masses does not
change.
-I
11-
A The gravitational force between the ends increases.
B The gravitational force between the ends decreases.
The gravitational force between the ends remains the same.
D The gravitational force between them decreases by one half.
The gravitational force between them doubles.

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x,y components step 4 step 5 step 6

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.

Suppose astronomers built a 140-meter telescope. how much greater would its light-collecting area be than that of the 10-meter keck telescope? express your answer using two sign
