b) How long is the pipe?
Capacitance and resistance network.
The focal lengths of the objective and the eyepiece in a microscope are 0.29 and 2.5 cm. what is the distance between the objective and the eyepiece?
Power lines at 20,000V (rms) are connected to a utility pole transformer. Find the ratio of the number of turns in the primary to the number of turns in the secondary
assume the roller coaster (h1 = 37 m, h2 = 13 m, h3 = 30) passes point A with a speed of 3.10 m/s. If the average force of friction is equal to one third of its weight, with what speed will it reach point B? The distance traveled is 55.0 m.
A cord of length 1.5 m is fixed at both ends. Its mass per unit length is 1.1 g/m and the tension is 11 N. What is the frequency of the fundamental oscillation
