The hubble space telescope is a reflecting telescope that was placed in orbit above the earth’s atmosphere, so its resolution would not be limited by turbulence in the atmosphere. its objective diameter is 2.4 m. for visible light, say λ = 550 nm, estimate the improvement in resolution the hubble offers over earth-bound telescopes, which are limited in resolution by movement of the earth’s atmosphere to about half an arc second. (each degree is divided to 60 minutes each containing 60 seconds, so 1◦ = 3600 arc seconds).

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.
