The force of attraction between a -130.0 c and +180.0 c charge is 8.00 n. what is the separation between these two charges in meter rounded to three decimal places? (k = 1/470 - 9.00 10°n. m2/c2 1uc = 106c)

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
