a block of mass 5.0 kg is pulled across a horizontal surface at a constant speed by a force 14 n directed at 35 degrees
A radio tuner is built by connecting an L=0.41mH inductor and variable capacitor in series with an antenna. The driving voltage is provided by the radiowaves that pass through the antenna, and the total internal resistance of the circuit is R=1.2O..
A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (3.0 m, 3.7 m) while a constant force acts on it. The force has magnitude 1.7 N and is directed at a counterclockwise angle o..
