when a electric potential difference is applied across the metallic wire ,the loosely attached free electrons start moving towards the positive terminal to the cell .this continuous flow of electrons
Why is a high impedance earphone better for a crystal radio?
thanks-Another way to look at it is that the Crystal set captures very little power and can, therefore, supply very little current.With th
Given |vector a| = 3, |vector b| = 5, and |vector a + vector b| = 7, determine |vector a - vector b|.
answer: 4.26
Can somebody please explain how you solve this question? Its too hard for me...-Wh
I have a school project and we need to put an egg in a milk carton and drop it off our schools clock tower. It has to be in a milk carton, thats the only rule. There can be padding and whatnot too.-fo

As you can see from the article below, it depends on the specific level or inclined plane as to the specific mechanical advantage. So neither is inherently superior.-It depends on the sizes of the lev
Like in lawnmowers, tractors, parking cars and others
It seems they are only used in TVs, toys and parked cars (except maybe some industrial applications)
Why is this?-While there are devices for indu
A wanderer hikes due east for 2 mi, then southeast for 3 mi, then due north for 6 mi, then southwest for 6 mi. She then notices a storm gathering. How far is she from her starting point?-Approximarely
Im not sure of the process or machine used to do this, but on the first season of The Colony a device was used to convert a low level of power into a higher level of power, just by putting it through
A savings scheme pays 5% per annum compound interest. A deposit of £100 is invested in this scheme at the start of each year.
a) Show that at the start of the third year, after the annual deposit has
I think I have that right.I have a device that has 4-20 mA printed on it.Should I read that as meaningthe device is 0.4amps?-no.... 0.4 amps is 400 milli-amps
your device draws just 4 milli-amps norm
I am trying to better understand oersted and amp per meter. I have done some research and from wiki founded 1 oersted = 1000/4π (≈79.5774715) ampere per meter. It then goes on to say, a wound with 79.
ok, before anybody gets excited, i have done TONS of research. but for some reason i cannot find a decent enough comparison. theyre either too biased or not in depth enough and basically said they are
