Coulomb's Law F = kqQr2 relates the force F between two charges q and Q, which are a distance of r units apart. Choose the formula that represents this when solved for k. A. k = r2FqQ B. k = Fr2qQ C. k = r2FqQ D. k = qQr2F

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

the answer is 2/54
