Which of the following is a chemical reaction? a. breaking a glass pane b. freezing water c. digestion of food d. cutting down a tree e. evaporation of rubbing alcohol reset

I believe that it could be either B or C, freezing water is where the water will freeze from the very low temperature, water can react to different tempertures but, digestion of food is obivously your digestive system from your food dissloving in your mouth to it disolving in your stomach because of your bodily acids. I dont know which one is corrcet but read over both and choose what seems to be more accurate to your question. Hope I helped :( good luck

C- digestion of food

Explanation:

Just had this on a test :)

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
