Runoffs from an uranium mine stockpile have contaminated the surface water in a location. this might cause health problems among people in the location. which of these is the best plan to solve this problem? select one: a. plant trees around uranium mines to absorb contaminants b. put fences around uranium mines to check the flow of contaminants c. wear protective clothing for prevention against harmful effects of radiation d. collect the runoffs in retention ponds for isolation and recovery of contaminants

The best plan to solve the problem of health problems among people, because of the contaminated surface water is to collect the runoffs in retention ponds for isolation and recovery of contaminants. Correct D

This is tn eonly option from the given that is the most efficient and prodcutive way to solve this problem.

multiply 2kg by latent heat of vap

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
