Calculate the viscosity of a fluid that would allow a pressure drop of 35 kPa over a 5 mlength of 0.75-in. stainless steel sanitary pipe if the fluid is flowing at 0.12 m3/h and has adensity of 1010 kg/m3. Assume laminar flow.
a near-sighted person might correct his vision by wearing diverging lenses with focal length f 50 cm. when wearing his
A pully system consists of a mass M = 3.5-kg block resting on a frictionless horizontal ledge. What is the acceleration of each block
how to Calculate the acceleration of the system. Assume the magnitude of the acceleration is the same during starting and stopping.
It is used to push a 0.50 kilogram block 50 centimeter along a horizontal frictionless track then up theta=30o incline which has a kinetic friction coefficient of 0.10. Compute how high above the track does the block rise
You bring a 350-g wrench into the house from your car. The house is 15 C warmer than the car, and it takes 2.52 kJ of energy to warm the wrench by this amount. Find (a) heat capacity of the wrench and (b) specic heat of the metal it's made from.
An explosion breaks an object initially at rest into two pieces, one of which has 1.6 times the mass of the other. how much kinetic energy did the heavier piece acquire
Block A in the figure weighs 1.60 N and block B weighs 3.10 N. The coefficient of kinetic friction between all surfaces is 0.300. Illustrate what is the friction force on block A?
In the Bohr model of the atom, the ground-state electron in hydrogen has an orbital speed of 2190 km/s. What is its kinetic energy
If the end of the crutch is a circle of radius 1.0 cm without the tip, and the tip is a circle of radius 2.5 cm, by what factor does the tip reduce the pressure
A hydraulic jack is made with a small piston 1.3 cm in diameter that is used to move a large piston 5.2 cm in diameter. how heavy a load can he lift with the jack
Copy the drawing and mark on it the location of highest bending stress. Make a three-dimensional Mohr circle representation of the stresses at this point. (Neglect stress concentration.)
Consider a charge distribution enclosed in a box with the same geometry as the box in question 2(a) and 2(b), but rather than having a constant charge density, the charge density varies inside the box with z as p(z) = k(z + d/2), where k is a con..
