If i wanted to generate a maximum emf of 20 v, what angular velocity (radians/sec, aka hz) would be required given a circular coil of wire with diameter 40 cm and 500 coils? the coil rotates through a magnet field of magnitude 9e-3 t which is directed such that the angle between the area vector and the magnet field vector varies from 0 to 2 π radians. group of answer choices

Alice added sodium chloride to water and stirred the water for several minutes. alice is most likely trying to demonstrate that ionic compounds a. are hard. b. can dissolve. c. are clear. d. can melt.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
