A vector has a magnitude of 8.0 units and forms an angle of 60° with the positive x-axis. The x-component of this vector is most nearly:
A force vector in a plane has a magnitude of 12.0 N and forms an angle of 135° with the positive x-axis. If this force is applied to a 6.0 kg object initially at rest on a frictionless surface, the acceleration component along the x-axis is most nearly:
In a series RLC circuit with R = 120 Ω, L = 0.2 H, and C = 100 μF operating at 60 Hz, the total impedance magnitude is most nearly:
