Is there another name for "the volume Swept through" in maths "Graphs" ? Is there another name for "the volume Swept through" in maths "Graphs" ? No matter how and where I search I can't find anything showing me how to get the "the volume swept through" of a graph and yet they ask it just...

The relationship between the quantity (in thousands of tons) of three types of ore which is mined on a certain day at a mine, is given by the following system of equations: r + s + t =12 2r -s +3t = 18 6r - 3s +t= 6 Determine the quantity of each type of ore which is mined using the...

So 2.54mm^2 would be 2.54mm^2 x10^-6 = 0.00000254m^2

Im sorry I might sound stupid but I am confused. So you can't just go 2mm^2/1000 = 0.002m^2 ? Should then say 2mm/1000*1000 ? Wouldnt that just complicated question even further? Thanks for the replies :)

Ok so I came up with this.. ITS a huge mess Aluminium Cable = R1 Copper Cable = R2 I =18.2A R1s = 78m R2s= 64m R1a = r^2 π=(0.9)^2 (π)= 2.54mm^2÷1000=0.00254421m^2 R2a = r^2 π=(1.05)^2 (π)= 3.4629525mm^2÷1000=0.0034629525m^2 R1Ωm= 0.018μΩm ×〖10〗^(-6)=0.000000018Ωm R2Ωm= 0.031μΩm...

A load taking 18.2A is supplied by aluminum and copper cables connected in parallel. The lengths of the copper and aluminium cables are 78m and 64m respectively. The diameter of the aluminium 1.8mm and that of the copper 2.1mm . The resistivity abd copper is 0.018uOHMm (Ohm.meter) and 0.031uOHMm...

An electric motor drives an electric generator.The 2hp motor draws 15A from a 120V D.C source and the generator supplies 5A to a 48Ohm LOAD. It is given that 1hp= 745.7W Calculate the motor efficiency. Calculate the generator efficiency. Calculate overall efficiency. Ok soo I...

1.A plate is to be nickel-plated to a thickness of 0.15mm in three and a half hours. The electrochemical equivalent of nickel is 0.305mg/C and the density of nickel is 8778kg/m^3 .Calculate the surface area of the plate that can be plated to the specified thickness with current of 12.4Amps...
