Please view PDF for schematic of circuit and more information on loads.
Load 1 is the 5 KVA load and Load 2 is the 10 KVA load. Loads 1 and 2 are operating at their rated voltages of 220 V rms.
a) Find Load 1’s real and reactive power
b) Find Load 2’s real and reactive...
On the datasheet for an LED I can see that peak current, for the specific model I am looking at, is 100mA pulsed at 0.1ms. So 135mA would definitely damage the LED. Looking at this datasheet, I would say you should be shooting for about 20 to 25mA to start.
Put a resistor in series between...
Ok, thank you for your advice. I guess i will do a bunch of questions to drill it into my brain. I wrote down those taylor series before your reply because i kept seeing them online. Well, at least i only have to memorize 4. Again thank you.
I can't seem to be able to come to the conclusion that you have gomunkul51 unless i follow the method used from the following site
I know i should probably just stay quiet and deal with it...
I seem to have forgotten how to express a series as a function. I took calc 2 over the summer so we rushed through everything and i don't think all that information got a chance to settle. So here is the question. I'm going to try using syntax but i will write it out as...
I have solved the problem, but it makes me feel good to see that a bunch of people viewed the thread and no replies. I assume it was a brain buster for the people who viewed it. Fact remains I couldn't find an exact value, but i achieved the desired decimal place accuracy.
Utilities companies usually use a separation between poles about 340 feet. These poles are 34 feet tall and due to restrictions due to maximum height of trucks using interstates and state routes, the minimum clearance is 20 feet (and also considering the increase of sag...
Ok, I believe i found my source of error. When solving for initial velocity equation (7) should turn out as following:
7) Vi = sqrt( ((g)(xf^2)) / ((2)(cos^2(angle))((-yi) - (xf)(tan(angle))))
I left out the cos^2(angle). I redid the calculations and yielded the answer in the back of the...
So the given data is as follows:
angle = 42 degrees
yf = 0m
yi = 2.1m
xi = 0m
xf = 17m
I used the given data to produce the following six equations where "t" is time and "V" is velocity and "g" is the acceleration due to gravity -9.8m/s^2.
1) Vfx = (Vi)(cos(angle))
2) xf =...
A shotputter projects the shot at 42 degrees to the horizontal from a height of 2.1 m. It lands 17 m away horizontally. Next, he gives it the same initial speed but changes the angle to 40 degrees. What effect does this have on the horizontal range?
I do need to use calculus. I need to use trigonometric substitutions and integration. The method provided by HallsofIvy is the one i must use.
I followed through with the integral but now I am stuck at trying to solve for X.
What I have is:
sin^-1(x/7)+sin(2(sin^-1(x/7))) = pi/6...
A circle of radius 7 inches is sliced vertically, parallel to the y-axis, into three pieces. Each piece has an equal area. What is the width, x-axis, of each piece?
f(x)= +/- sqrt((r^2)-(x^2)) where "r" is the radius.
The Attempt at a...
