Two wires are parallel, and one is directly above the other. Each has a length of 55.8 m and a mass per unit length of 0.0260 kg/m. But, the tension in wire A is14.6×102 N, while the tension in wire B is 2.31×102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much time does it take until the pulses pass each other?
Steam enters a nozzle operating at steady state with p = 40 bar and T =400oC, and a velocity of 10 m/s. The steam flows through the nozzle with negligible heat transfer and no significant change in potential energy. At the exit, p2 = 15 bar and the v..
A child on a boat throws a 5.40 kg package out horizontally with a speed of 12.0 m/s. determine the velocity of the boat immediately after, assuming it was initially at rest. The mass of the child is 26.5 kg and the mass of boat is 55.5 kg.
A diving board of length L = 3.00m is supported at a point a distance 1.00m from the end, and a diver weighing 530N stands at the free end. Find the force at the end that is held down
A 1,500kg Jeep is parked on a 30? slope, facing uphill (this is been done in right now in "Camp Jeep" en el Hiram Bithorn). Find the normal force exerted by the road on the front wheel
An artificial lens is implanted in a person's eye to replace a diseased lens. The distance between the artificial lens and the retina is2.82cm. What is the power of the implanted lens
A mass m = 12.0 kg rests on a frictionless table and accelerated by a spring with spring constant k = 4827.0 N/m. The floor is frictionless except for a rough patch. For this rough path, the coefficient of friction is ?k = 0.41. The mass leaves th..
