Two forces, f⃗ 1 and f⃗ 2, act at a point. f⃗ 1 has a magnitude of 8.00 n and is directed at an angle of 60.0 ∘ above the negative x axis in the second quadrant. f⃗ 2 has a magnitude of 5.20 n and is directed at an angle of 53.6 ∘ below the negative x axis in the third quadrant.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

Acertain radio station broadcasts radio waves that have a wavelength of 298cm what is its broadcast frequency?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
