The graph shows changes in GDP in the United States from 2009 to 2011. A bar graph titled Annual growth in U S G D P has the year on the x-axis, from 2009 to 2011, and percentage on the y-axis, from negative 6 to positive 4 percent. The percentage of growth for the services producing sector in 2009 was negative 3 percent, in 2010 it was 2.3 percent, and in 2011 it was 2.1 percent.

How did the contribution of the services sector to GDP change between 2009 and 2011?

It rose by less than 1 percent.
It fell significantly.
It rose significantly.
It stayed exactly the same.

It rose significantly.

Explanation:

Looking at the description of the map shown in the questionnaire above, we can see that there is a big difference in the contribution of the service sector to GDP between 2009-2011. In this case, although this contribution decreased in 2011 compared to 2010, the situation between 2011 and 2009 is completely different. This is because the service sector made a considerably greater contribution than the 2009 contribution.

it fell by 2.3%

Explanation:

ek = (m.v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) v2/2

ek = (200 + 250) 2,32/2 = 450*5,29/2 = 1190,25 j
