Hi, I have been set a sheet of questions for homework and there are two which I cannot do. Any help you could give would be greatly appretiated. 1) I have tried doing this but keep getting into cycles of inputting equations into it and just going around in circles. 2) This is a two...

Question: A pyramid with horizontal square base, 6.00m on each side and a height of 4.00m is placed in a vertical electic field of 52.0 N/C. Calculate the total electric fluc through the pyramids four slanted surfaces. I know you can figure out the flux through the base = 36 m * 52.0 N/C...

Hello there ! I have been trying to figure the following problem out but unfortunately I have not had any obvious success. It is about Kinetic Energy: A stone is falling from the roof of a house down to the ground. In the last second of the fall, the stone's energy increases of 293 J. How high...

1 Celsius= 274.15kelvin Right So 274.15+274.15=548.30 Kelvin(2 Celsius) But 2 Celsius Is= 273.15 I am Confused Help

This is my 1st semester in 2nd year course, sounds to hard and I do worry. Did anyone study something like this description. ELE 302 Electric Networks Three phase circuits- 3-phase voltages, Y and delta-connections, balanced three-phase systems, power calculations, two-wattmeter power...

it is said in our book that when matter undergoes changes whether physicaly or chemically, the atoms are merely rearranged. no atom is created nor destroyed. (the law of conservation of mass) but isn't it that we are made of atom then if I am made up of atom an atom is created when I am...

Electrical Engineering Program was very, very hard. Six courses per semester, it was suicidal but manageable. I could not imagine that it was going to be so dificult in my first year of engineering program. Not many students are left in the program. I was a top student in high school but...

Hi everyone. Thanks for reading this post. I'm looking for a little guidance on how someone whose training is outside the hard sciences can break into a scientific career path. I know that it will inevitably involve going to back to school, but perhaps there are jobs I could do in the mean...

I have an occasion to earn some money over the summer doing that building insulation or something like that, and I'm not sure whether I can handle it, meaning is it hard to do? After all, I don't know what insulation really is but from what I got by google, you just put some stuff to warm up a...

g(x) is a function of x that we do not know its form. y(t) =(1/2) integral 0-->t [ sin(2t-2x)*g(x) ]dx i tried to use integration by substitution and by parts but the problem is that g(x) has an unknown form. the actual problem is that y" +cy' +dy = g(t) y(0) = y0 y'(0) = y'0...

For one of my classes I need to implement a model of a charged particle that is giong through electric and magnetic fields. I can assume these constants: m=1 q=1 x(0)=0 t-scan: [0 1] Now the questions: 1) Simulate the constant acceleration analytic case and plot the result. Add the...

When I was in college I had a recording of The ThreePenny Opera, the well known Broadway/English translation by Marc Blitzstein, and some kids from Germany who'd heard it complained that it was a poor translation: the original was much down and dirtier, more crude and gritty. Every once in a...

Ok, so up until this morning I thought my hard drive was only 20GB (Dell Latitude D800), because that is the size of my C drive and no other drives are visible when I open My Computer. But this morning I was thinking there is no way my computer only came with 20GB, so I went into the System...

2.5" Mobile Hard Drives Why its capacity is still at about maximum 100 GB, seldom has 120GB. When can we increase it to >200GB ? Can we increase the platter diameter to 3.5" but the drive remain flat so that it can fit nicely into the notebook? This will increase its capacity.:biggrin:

I can't figure this one out: A point of the surface of a solid sphere (radius = R) is attached directly to a pivot on the ceiling. The sphere swings back and forth as a physical pendulum with a small amplitude. What is the length of a simple pendulum that has the same period as this physical...

Ok, I've been looking around for a answer for this , but haven't found one. So in hope for some help, ill post the problem here: A pipe has the form as a half cylinder. On the top of the cylinder its placed a item that can slide frictionfree on the cylinder. The cylinder gets a microsmal...

This week the water was out twice, the power was out for a few hours, and we just had a magnitude 5.8 earthquake 'bout five miles southeast, and 30 miles down. It was scary. We get earthquakes a lot 'round here. This one seemed pretty calm, then for about .7 seconds it was crazy! Floor musta...

I commonly hear the words "Physics" and "Genius" combined in many sentences, which seems to be a bit of a misnomer, considering that most of physics is rather simple, and only gets complicated once you have to apply hundreds of possible changing factors in a problem. Or am I just being...

Hey everyone, How does sodium carbonate soften hard water? Thanks, Lou

I don't really know what MIH's name is all about, but I think i should change my name to math is hard II. I hate math, math hurts my brain :cry: :cry: :cry: :cry:

For this problem assume the "EM spectrum of astrophysical relevance" is between 1m and 10^-3nm. Calculate the fraction of the visible light by assuming a) a linear scale and b)a logarithmic scale. Explain the difference.. hur? I'm guessing this is one of those math skills I've either...

I love math, but it seems love does not conquer all: last semester, my average turns out to be B+, the bare minimum required to stay in the honours program. I told my professor that I study already a lot, and he told me that perhaps I was studying the wrong way. So, how does one study for math...
