well... the problem only gave me the first part of the equation which was the CO2 + Mg. This is the chemical process that occurs when dry ice is mixed with burning Magnesium pellets, which creates this fire work type of reaction. I figured that the magnesium and carbon will combine and release...
I don't know if I solved this problem correctly.
Balance the equation:
CO2+ Mg -> MgC + O2
Is this the right end result and can someone help me figure out the state of matter for each.
Can some one help me with this Milliken oil drop problem.
Data from a Milliken oil drop experiment are given below. Calculate the value of the charge on an electron from this data:

Here's the problem: Can someone help me start it off?
A long straight solenoid of cross-sectional area 6 cm^2 is wound with ten turns of wire per centimeter, and the windings carry a current of 0.25 A. A secondary winding of two turns encircles the solenoid. When the primary circuit is...
WOW ur a genius! Will u be my homework buddy? LOL Thanks a lot for the help even though it's like uber late there in NJ. I might be bugging you for more physics stuff. Hope you don't mind.
lol.. ur funny. Well... here's what I have now:
a) emf =1.00 V
b) I=5.00 Amps, Fmag=1.25N
c) Fv=5.00j
wait.. u got me.. crap.. I keep messing up. Thnx for dealing with my overwhelming stupidity.
Ok.
a) emf= Bvl --> (4.00m/s)(0.500T)(0.0500m) = .100 V
b) I=emf/R --> (0.100V)/(0.200 ohms) = 0.500 A
Fmag= IBl --> (.500Amps)(0.500T)(0.0500m) = 0.0125N
Ummm... here's the entire problem:
A conducting rod AB makes contact with metal rails CA and DB. The apparatus is in a uniform magnetic field 0.5 T, perpendicular to the plane of the diagram. The rod is 50 cm long.
a)find the magnitude and direction of the emf induced in the rod when it is...
I don't quite understand what I'm suppose to do in this question:
--> Compare the rate at which mechanical work is done by the force (Fv) with the rate of development of heat in the circuit (i^2 R).
Here are my homework problems. I did most of them, but I don't understand how to do the others.
1. A rod of length 0.40 m moves in a magnetic field of magnitude B=1.2 T. The emf induced in the moving rod is found to be 2.40 V.
a)what is the speed of the rod?
b)if the total circuit...
Here is a problem that I don't quite understand.
P: Two hikers are reading a compass under an overhead transmission line that is 5.0 meters above the ground and carries a current of 400 Amps in a direction from south to north.
a. Find the magnitude and direction of the magnetic field at...
Well... since I knew how much volts there is, I figured that it is faster to just use that formula where k is the Coulomb constant (8.99x10^9 Nm^2/C^2), then just solve for the radius. Is it possible to use this equation like that?
I'm confused if I am using the right equations to solve this problem.
P: A singly charged Li^7 ion has a mass of 1.16x10^-26kg. It is accelerated through a potential difference of 500 Volts and then enters a magnetic field of 0.4 Teslas, moving perpendicular to the field. What is the radius...
So what you're trying to say is that since I know the voltage, I should multiply it by the charge of an electron (1.60 x 10^-19 C). By doing so, I will get the total energy, which I can use in the kinetic energy equation to solve for the velocity. That sounds great. So there's no need for me to...
Sorry, I don't know the answer. I wasn't sure about the velocity part either. Because I used U=1/2 mv^2, which is for springs, i think. How did u solve it? And the V= U/q is for volts.
