Asingle force acts on an object. the components of this force act along the +x-axis and the –y-axis. the single force that will bring the object into equilibrium has components that act along the a. +x-axis and +y-axis. c. -x-axis and +y-axis. b. +x-axis and -y-axis. d. -x-axis and -y-axis.

If two metal balls each have a charge of -10^-6 c and the repulsive force between them is 1 n, how far apart are they? (coulomb's constant is k = 9.0x 10^9 n-m^2/c^2? 9.5 m 9.0 mm 9.5 cm 0.9 m .

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?
