Three forces in the x-y plane act on a 8.20 kg mass: 10.30 N directed at 29o, 7.00 N directed at 143o, and 11.30 N directed at 250o. All angles are measured from the positive x-axis, with positive angles in the Counter-Clockwise direction. Calculate the magnitude of the acceleration.

Current 1 of 8.4 a runs for 240 seconds and then stops. current 2 is 10.5 a. how long does current 2 have to un to deliver the same amount of charge as current 1? 88.28 192 s 2016 s 21,000 s
