A.) Briefly describe three ways that distances to stars can be measured.
b.) Name an object, not man made , that emits light in pulsars similar to those from a pulsar. Any wavelegnth is okay. Could we detect these pulses if they came from Jupiter? From a nearby star?
c.) Name a type of expansion (or expanding object) that does not obey Hubble's law.
A 40 kg block is at rest on a frictionless horizontal surface and is attached to one end of a horizontal spring, which has a spring constant of 500 N/m. Find the maximum elastic potential energy stored in the spring after the collision
Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
