(WILL GIVE BRAINLIST) Why is solar energy unevenly distributed throughout the world? A. The amount of sunlight a place receives depends on its location on earth and the season. 
B. The amount of sunlight a place receives depends on the speed of wind there.   
C. The amount of sunlight a place receives depends on the oil and minerals found there.  
D. The amount of sunlight a place receives depends on the number of trees there are. 

A

Explanation:

You will see more solar panels in California because it is sunny often, rather than in Michigan, because the winters are dark and there is less sun. There fore making it less efficent. The other answers make no sence because they do not effect solar energy.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

overcharge is the right answer system
