Only Physics i write it together.
556611 : So more heat produced lor. Because high resistance = More heat loss to surrounding.  This post has been edited by abang brother: Nov 27 2010, 03:21 PM |

QUOTE(:+:DarreN:+: @ Nov 27 2010, 12:58 PM) there's a trick to that. if your calculator is 570, you can press Mode and select "Rad." that way, when you calculate angles, the values are in radians. Herm, how again the Rad? yes. this also means that buoyant force = weight of fluid displaced = weight of object  |

QUOTE(1malaysia @ Nov 27 2010, 03:24 PM) angle x pi/180 = rad. Not that lah guys rad x 180/pi = angle. I mean if 180 = Pi 360 = 2Pi if 135? = 3/4 Pi i just donno the 45 etc |
