A certain spaceship has a speed of 176,348 mi/hr. What is its speed in light-years/century? a light-year is the distance that light travels in one year with a speed of 186,000 mi/s.

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.

mistakes are ok

answer; how far out of place which the object finished relative to the starting location;
