Susan's 12.0 baby brother Paul sits on a mat. Susan pulls the mat across the floor using a rope that is angled 30 degrees above the floor. The tension is a constant 31.0 and the coefficient of friction is 0.210. Use work and energy to find Paul's speed after being pulled 3.30 .
What is the reaction that occurs with hexanal and propanol (give both the hemiacetal and acetal products)?
A conical tube of length 8 m fixed vertically with its smaller end upwards. The velocity head and pressure head at upper ends are 1.27 m and 2.50 m respectively.
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
Calculate the minimum flow rate (m^3/hr) of river water needed to acheive pre cooling hot, pasteurized liquid prodcut assuming that 10% heat is lost to the surroundings during exchange and that the water temp after cooling should not exceed 25 deg..
Introduction to management science, The Dynaco Manufacturing Company produces a particular product in an assembly line operation. One of the machines on the line is a drill press that has a single assembly line feeding into it.
Briefly describe electron and hole motions in a p-n junction for forward and reverse biases; then explain how these lead to rectification.
An open rectangular channel is 50 feet wide, flowing at a depth of 5 feet, and is carrying 1000 cubic feet per second. What is the maximum step height than can be placed into the flow without disturbing the upstream depth, without acting as a chok..
We would continue embankment work even if winter season and my question is what is swelling amount of compacted soil for 30cm thickness and 95% compaction degree by freezing.
A drinking water treatment plant will be designed to process a flow of 15,000 m3/d. The sedimentation tank will have a residence (detention) time of 4 hours and the overflow rate (Q/A) of 16 m 3 /m 2 -day. Estimate the required surface area (A), an..
Cancer is the uncontrolled growth of abnormal cells in the body resulting in tumours that can be benign or malignant (cancerous cells). A proper treatment is necessary to fight with this serious disease.
The shaft diameter is 100 mm. Calculate the largest principal stresses and maximum shear stress that will occur in the shaft.
The machine part ABC is supported by a frictionless hinge at B and a wedge at C. Knowing that the coefficient of static friction is 0.20 at both surfaces of the wedge, determine:
