Answer:
521.8 V
Explanation:
The RMS value of the voltage of an AC signal is given by
where
is the peak voltage, which corresponds to the amplitude of the AC waveform
In this problem, we know the RMS voltage
Therefore, we can re-arrange the previous equation to find the peak voltage (the amplitude of the waveform):
Answer:
Explanation:
A free-body diagram is a sketch of an object of interest with all the surrounding objects stripped away and all of the forces acting on the body shown. The drawing of a free-body diagram is an important step in the solving of mechanics problems since it helps to visualize all the forces acting on a single object. The net external force acting on the object must be obtained in order to apply Newton's Second Law to the motion of the object.
A free-body diagram or isolated-body diagram is useful in problems involving equilibrium of forces.
Free-body diagrams are useful for setting up standard mechanics problems.
