Apipe open only at one end has a fundamental frequency of 266 hz. a second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. now when both pipes vibrate at their fundamental frequencies, a beat frequency of 10 hz is heard. how many centimeters were cut off the end of the second pipe?

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?
