Two tuning forks produce sounds of wavelengths of 3.4 meters and 3.3 meters.
given that the speed of sound in air is 340 m/s, approximately what is the beat frequency produced by these two tuning forks?

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.
