In regard to the effectiveness of the number of "work" or "training" sets of repetitions done permuscle group/exercise for a typical 12 week - 6 month program, it is not true that: a. one set increases strength and muscle size. b. three sets is usually more effective than one set for increasing strength and muscle size. c. four sets produces four times the training effect of one set, e. g. 4 times as much weight for one set or 1rm or 4times more reps for one set until failure. d. none of the above are true.

What happened to rosalind franklin in 1956?

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
