resistance in the right gap at a distance of 42 cm from
the left end. What is the value of the unknown resistence?-Let
P = 42 x p
Q = (100 -42) x p = 58 x p
Now
P/Q = R/X
Or X = Q/P x R
= [(58 x p)
Acentimeter ruler, balanced at its center point, has two coins placed on it, as shown in the figure. One coin, of mass , M1= 10g, is placed at the zero mark; the other, of unknown mass M2, is placed a
How does: more coils, curved poles, electromagnets: effect the effectiveness of a.c generators?-This question is far too big to answer in a few words.
All that I can say is that effectiveness might me
How much pounds (LBS) per square foot of force at what speed. If I was to hold a square pane of glass (1 squ ft area) directly into the wind while I am in a car traveling at 60 MPH (60 MPH wind)-The d
If a normal radioactive element such as Plutonium would give of high amounts of radiation, theoretically, what would an anti-plutonium do?
Thanks.-It should give also high amounts of radiation, howeve
Both seem to describe how how receptive a material is to developing a magnetic field when in the presence of a magnetic field.-Your suspicion that both terms describe the same thing is correct. There
I know refraction is the bending of light when entering one medium to another. -bends towards the normal from less dense medium more dense medium (air to glass) and so opposite is also true..
BUT.What
-1 - i-So that you can follow what I do, Ill so this the long way.
1 * i = i
i * i = i^2 = -1
i * i * i = i^3 = -i
i * i * i * i = i^4 =-1 * -1 = 1
i^5 = i
i^6 = -1
i^7 = -i
i^8 = 1
So you can see
Hello. I got a question on my homework: A round closed pipe with radius R gets constant angular velocity clockwise(the pipe is horizontal) W1. A little particle with mass m can slip inside the pipe(th

In my music theory class, my teacher said that all sound is the result of vibrations. Any time something vibrates, it creates a sound wave. But I have two questions about that.
1. If that is so, then
