the electric power P generated by current varies jointly with the voltage drop V and the current I. If 6.00A of current in a 220v circuit generate 1320 W of power, how much power do 8.00A of current in a 115v circuit generate?
here what I got so far:
current v W...
a copper wire 750ft long has resistance of 1.563. How long is a copper wire of the same cross-sectional area whose resistance is 2.605. Note: the resistance of these wire is proportional to their length.
attempted to solve:
750ft/1.563=x/2.605
then cross multiply
750 * 2.605 =...
a machinist needs to drill five holes in a circular plate. the centers of the holes must be 8.0 cm from the center of the plate and be spaced in a circular pattern equidistant from each other. How far apart (straight-line distance will the centers of the adjacent holes be placed?
some help...
the pathway for a mineshaft is described as follows: The first shaft extends north and down at an angle of 3.5 degree for 225ft to a vertical shaft which 125ft long. A third shaft then extends north and down at an angle 6.8 degree for 175ft. What is the total depth below ground level at the end...
