A circuit with three 30 Ohm resistors in parallel is connected to a 12 volt power source. What is the total current across each resistor? [?] amps

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Compare the patterns of the two waves shown in the image. which statement is true about these waves?
