That's the one part of my project I can't seem to figure out, but more generally, how would I figure out the measurements to construct an 8-foot-wide concave semi-globe using 24 flat, long, bendable panels that are 3/16" thick? I know that the panels will be 12.56 feet long, and I know they will be 0.523333 feet wide in the middle, but they taper off at a curve until they have zero width at the poles. I need to figure out the width of the panels at each increment, such as every 12 inches, or maybe at 10%, 20%, and so on. Any takers?

The no load voltage in the voltage divider circuit shown below is 20 V. The smallest load resistor that is ever connected to the divider is 48 kilo ohms. When the divider is loaded, V0 is not to drop below 16 V.
a) Design the divider circuit to meet the specifications just mentioned. Specify the numerical value of R1 and R2
b) Assume the power ratings of commercially available resistors are 1/16, 1/ 8, 1/4, 1, and 2 W. What power rating would you specify?

Can your regular idea or imaginative idea or your point of view ever be better than that of the computer programmer? Or the computer programmer's idea or point of view is always smarter than you.

1. Describe bichromatic analysis including the principle, arrangment of components and advantages. Extrapolate the principle to multiple-wavelength spectrophotometry. Then list examples of comon interferences that can be corrected using bichromatic analysis.

2. The difference between single beam and double beam spectrophotometry?

Silicon is the most abundant element on Earth and is the primary component in sand. Another product made from sand is glass. I learned in the past that glass industry is picky where they mine the raw sand. I wonder if sand for making silicon chips requires equal or higher quality.

the aztecs built large wooden rafts on which they placed soil and plants. the plants grew to the bottom of the lake. soil then naturally filled in the root system. thus creating land where there once was water.

We have a building where services, meeting, etc... are held. There are 95 individual lights and 6 florescents, controlled on 14 different switches. The average number of lights for each switch is approximately 7. The most being 14, least is 4.

The 6 florescents are only on 2 switches at the moment. The first has 14 lights and 1 florescent. The second has 6 lights and 5 florescents.

How can I group all the lights together so I can turn them off/on using only one dimmer switch, without tripping any circuit breaker?

Thanks,
Christopher

p.s. It would also be nice if I could still use those 14 switches or at least group them together. (i.e. stage left/right, audience left/right, media room). Media room has the flourescents.

do you just use pins one and two to vary the resistance ans leave pin three alone? Or do you ground pin three?

Ok so technically engineers aren’t exactly the best writers, being more science oriented. So my question to you is why should engineers be better writers? Of course we know they need to get their thoughts across through writing, or a bridge can collapse killing millions, but what are some other reasons? I will give the best answer to someone with a really thorough and detailed explanation.

A custom built pool measures 10.0 ft long by 50.0 ft wide. The pool has a constant depth of 12 ft.The contractor filled the pool with 37,500 kg of water. You stand 5 ft 9 in, is the water over your head?
(density of water = 1.0g/cm3 1ft = 12 in 2.54cm = 1 inch )
