Water (density = 1x10^3 kg/m^3) flows at 15.5 m/s through a pipe with radius 0.040 m. The pipe goes up to the second floor of the building, 3.5 m higher, and the pressure remains unchanged. What is the speed of the water flow in the pipe on the second floor?

, 
- Pressures of the water on the first and second floors, measured in pascals.
- Density of water, measured in kilograms per cubic meter.
, 
- Speed of the water on the first and second floors, measured in meters per second.
, 
- Heights of the water on the first and second floors, measured in meters.![\frac{\rho\cdot v_{2}^{2}}{2} = P_{1}-P_{2}+\rho \cdot \left[\frac{v_{1}^{2}}{2}+g\cdot (z_{1}-z_{2}) \right]](/tpl/images/0913/5905/60ce8.png)
![\rho\cdot v_{2}^{2} = 2\cdot (P_{1}-P_{2})+\rho\cdot [v_{1}^{2}+2\cdot g\cdot (z_{1}-z_{2})]](/tpl/images/0913/5905/a8193.png)

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.
