The question is:

An apple floating in water displaces 50 cm^3 of water (one cm^3 of water has a mass of 1.0 grams). What is the buoyant force on this apple?

How do I work this one out. I know that d=m/v, but would this formula even apply?

1) find 2 points that has a distance of 5 and a slope of 3/4 to the point (2,3)

2) find the interior angles and area of the triangle with points (4,2), (0,1), and (6,-1)

I already tried to answer this problem but my angles has negative, so it wont be equal to 180 degrees

Hi! I Just took an employee drug test today and am a little worried about the .5 mg of ativan I took a week and a half ago. That is all I took, and it is not my prescription, it's my sister's. It was also a hair test. Will I not pass even though I took such a small dose? Do all drug test test for benzodiazepines?
