During her speed walking training session, Megan walks 1200 m in 450 seconds. a) What is her speed in m/s?( Round your answer to the
nearest tenth) b) Using the conversion factors 1m = 3.3 ft, 5280 ft = 1
mile, and 1 hour = 3600 s, determine Megan's speed in miles per hour.*

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

this would be about 43%

they us to move forward and backwards
