A rectangle commercial building must be laid out 200.00 ft wide and 300.00 ft long. if the steel tape used is 100.02 ft long under standard conditions, what distances would be laid out?
Find the speed of light in flint glass (refraction index 1.67). Use 2.99792x10^8 m/s for the speed of light. Find the speed in light in zircon
Explain the decision by price takers to continue to operate, temporarily shut down, or go out of business, when faced with price below average total cost.
A fan is to be selected to ventilate a bathroom whose dimensions are 2 m x 3 m x 3 m. The air velocity is not to exceed 8 m/s to minimize vibration and noise. The combined efficiency of the fan-motor unit to be used can be taken to be 50 percent.
A ray of light has an incident angle of 30.1 on a block of quartz and an angle of refraction of 20.4. what is the index of refraction for this block of quartz
Do the benefits of free and easy access to copyrighted materials by individuals, organisations and/or the community outweigh the drawbacks?
Discuss the conditions that characterize pure competition (a price taker market) and explain how and why price takers maximize profits at the quantity for which marginal cost, price, and marginal revenue are equal.
A pilot claims to have seen a UFO moving initially at a speed of about 465 m/s in an easterly direction and then, Compute the UFO's average acceleration during the turn
Assume the flow is incompressible, irrotational, quasi-steady and the only body force acting is gravity. Determine the pressure, pb, required to increase the jet velocity by 50% relative to the value realized for atmospheric pressure, pa, in the u..
Describe and analyze an algorithm to determine, given the initial sequence of cards, the maximum number of points that you can collect playing against a perfect opponent.
Determine the (a) the coefficient of statics friction between the hawser and the bollard. (b) the number of times the hawser should be wrapped around the bollard if a 20000 pound force is to be resisted by the same 80 pound force
A two post in ground car lift uses compressed air to force water under two aluminum pistons that move in unison (both pistons at same elevation) to raise and lower the vehicles.
A thick steel sheet of area 440cm3 is exposed to air near the ocean. After a one-year period it was found to experience a weight loss of 880g due to corrosion. To what rate of corrosion in mm/yr dose this correspond
The volume of water in a reservoir is often expressed using the unit of acre-foot. A volume of 1 acre-foot is the amount of water covering an area of 1 acre to a depth of 1 foot. Lake Mead is the largest man-made lake in the United States.
Use the Muskingum method to route a flood through a reach a river. The base flow is 100 cfs, and the incoming flood flow increases 50 cfs every 2 hr over a 6 hr period and the subsides at the same rate.
Compute the maximum acceptable service load on an A36 steel plate tension member 1/4in.x12in. having a single line of holes parallel to the direction of loading. The load is 25% dead load and 75% live load, and 7/8in. diameter bolts are used.
A freeway exit ramp has a single 12-foot lane and consists entirely of a curve with a central angle of 90 degrees and L=628 feet. If the distance cleared of obstacles is 19.4 feet from the centerline, what design speed was used
how many cubic feet of seawater, density 60 lb/ft^3, must be processed to recover 1 ton of magnesium, 1,272 ppm?
An electrostatic precipitator (ESP) is being designed to collect flue gas particles at a power plant. The following information has been collected: electric field intensity = 100,000 V/m, and average particle charge = 0.30 fC (1 fC = 10-15 C).
