Awire of length 17.6 cm carrying a current of 5.95 ma is to be formed into a circular coil and placed in a uniform magnetic field of magnitude 4.74 mt. the torque on the coil from the field is maximized. (a) what is the angle between and the coil's magnetic dipole moment? (b) what is the number of turns in the coil? (c) what is the magnitude of that maximum torque?

Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified? the experiment tested too many variables. the control group was not treated the same as the experimental group. the sample size of twenty-four petri dishes is not large enough. the single type of bacteria is not adequate to make any conclusions.
