An experimental analysis of the natural oscillations in a particular structure shows the dominant frequencies of interest appear at below 200 Hz. However, frequency information also exists at 350, 450, and 750 Hz. If the signal is sampled at 400 Hz, how will the information in the aliased frequencies appear in the sampled data

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
