Gamma rays may be used to kill pathogens in ground beef. One irradiation facility uses a 60co source that has an activity of 1. 0×106ci. 60co undergoes beta decay and then gives off two gamma rays, at 1. 17 and 1. 33 mev; typically 30% of this gamma-ray energy is absorbed by the meat. The dose required to kill all pathogens present in the beef is 4000 gy.

An independent variable that the student controls during the experiment. (i'm not 100% sure this is correct, so i'm sorry if it's wrong)

Are there options? otherwise, i’d say afghanistan, cyprus, comoros, eritrea, and more are a couple examples of oil-dry countries. let me know if one of those was an option!

With any turning vehicle, the rear wheels follow a shorter path than the front wheels. the longer the vehicle is, the greater the difference will be. truck drivers initially swing out before making a turn. what isn't shown in this illustration is as car straightens out, the front wheels must travel a greater distance and the tail end drags on the shortest path.

Ibelieve the correct answer is c
