A block weighing 10 newtons is on a ramp inclined at 30° to the horizontal. A 3-newton force of friction acts on the block as it is pulled up the ramp at a constant velocity. The force applied to pull the box up the ramp acts parallel to the

incline. Draw the FBD for this problem and determine the magnitude of the force applied.

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 .

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth
