a) E=v/l ---> E = (12/3)*1000=4000 (Volt/meter)\n\nb) v ~ 1/r ---> v2=12*3/5=7.2 Volt\n   E=(7.2/5)*1000=1440 (Volt/meter)\n\nc) w=int(f.dx)=int(Eqdx)=int(vqdx/x)=int(36qdx/x^2)\n\n    = 36q*(-1/5+1/3)=72q/15\n\nq=4*pi*e*l*v/2=2*3.14*8.854*10^(-12)*0.003*12 = 200*10^(-12)\n\n\n---> w=960*10^(-12) J

1) assuming it's inversely proportional then you have multiplied by m+2/m so it's dm/(m+2)\n2)(m+2)d/m

Use your buffering equation and plug in the numbers you know to get your answer.  You might have to do reverse calulations to find your answer.

Since this is college algebra, it should be tough, but I'm having reading errors on the problem.\n\nCan't you just simply it down?\n\n8.5 = log (B/10^-16)\n\n10^8.5 = B/10^-16\n\nB = 10^-7.5

ignore the decimals when u originally do the problem, then however many deciams there are in both of the decimals you're multiplying is how many there will b in the answer. i.e. if you multiply 6.78x4.234 together the answer will have 5 numbers behidnthe dceimal point

would you like to supply me with some formulas? im out of grade 12 physics and i forgot most of the formulas. trust me from experience, just plug numbers into a formula and things will work\n\nF=mg = ma\nFk=μkN\na= vf^2 - vi^2 / 2d

[ (50000 x 2.4)+(25000 x .8) ] / (50000+250000)=1.8\n\nThe remainder of the info in the problem is not necessary.

2.5 m= - 25.. are you trying to solve for M.... \nand -3.25t=-3.11 i am assuming you are trying to solve for T?\n\nfor the first one... 2.5m/2.5=-25/2.5 so m = 10\n\n2nd one .. -3.25t/-3.25= -3.11/-3.25\n\ni don't know if this is what u looking for

SOrry, I can't help you. If I had the formulas I could do it, but there is no way I remember that off the top of my head! Good luck

Problem 1:\n\n1912.50/45,000 = x/60,000\n45,000x=60,000*1912.50\n45,000x=114750000\nx=114750000/45000\nx=2550\n\nProblem 2:\n(2000/3 = 3300/x)*2\n(2000x=9900)*2\n(x=9900/2000)*2\n(x=4.95)*2\nx=9.9 seconds\n\nThese solutions are solving for x algebraically, but are the long way.\n\nAs mentioned above, an easier way is to figure the percentage of each and then multiply.\n\nSo $1,912.50 divided by $45,000 = .0425.  Multiply this by $60,000 (60,000*.0425) = $2,550.\n\nThe same can be applied to the number of seconds.\nIt takes 3 seconds to print 2000 characters...3/2000 = .0015 (or 1 character every .0015 seconds).  Then multiply this by 3300 to get the time for 1 page = 4.95 seconds.  Then multiply by 2 to get the time for two pages: 4.95*2 = 9.9 seconds.
