A landscape architect is planning an artificial waterfall in a city park. Water flowing at 0.518 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.55 m high and falls into a pool (see figure). (b) To sell her plan to the city council, the architect wants to build a model to standard scale, one-seventeenth actual size. How fast should the water flow in the channel in the model?

Half Life

The concept of Half Life has numerous practical applications some of them includes figuring out the effective drug dosage to finding out when a radioactive becomes safe to use. If you look for a career in Nuclear Physics you will need this concept.
