Ship moving initially at 10.7 m/s due North, drifts due NE at the same speed. To correct the bearing, the captain accelerates the engine and turns the rudder NW. If the engines deliver a constant acceleration of 4.4 m/s2, how long will it take to assume the original course again?
A 90° elbow is used to direct water (? = 1000 kg/m3) flow at a rate of 25 kg/s in a horizontal pipe upward. The di-ameter of the entire elbow is 10 cm. The elbow discharges water into the atmosphere, and thus the pressure at the exit is the local ..
A horizontal 5-cm diameter water jet with a velocity of 18 m/s impinges normally upon a vertical plate of mass 1000 kg. The plate rides on a nearly frictionless track and is initially stationary. When the jet strikes the place, the plate begins to..
A very large plane of charge is oriented horizontally and has a constant charge distribution over the plane. A small insulating ball has charge +8.78 nC and mass 0.076 g. If the levitates 2.62 cm beneath the plane, and remains stationary, what is the..
A tuning fork with a frequency if 536 Hz is placed near the top of a tube opened at one end and closed at the other end. The water level is lowered so that the length of the air column slowly increases from an initial value of 20.25cm. Determine the ..
If two adjacent natural frequencies of an organ pipe are determined to be 475 Hz and 575HZ. Calculate the fundamental frequency and the length of the pipe.
Two circular metal plates of radius 0.21 m and thickness 8.3 mm are used in a parallel plate capacitor. A gap of 3.9 mm is left between the plates, and half of the space (a semicircle) between the plates is filled with a dielectric for which ? = 10.9..
The fundamental frequency of an organ pipe corresponds to 262 HZ. The third resonance of a closed pipe has the same frequency. What are the lengths of the two pipes
