In predicting the motion of tsunamis generated in the sea, and interacting with shoreline objects. a ripple tank is used to generate straight waves in region a that travel toward region b, which is separated from region a by a straight boundary. the frequency of the generator is 2.5 hz, and the waves travel in region a with a speed of 15 cm/s. if the wave fronts in region a strike the boundary at 20, and the wave fronts in region b leave the boundary at 50, (a) use snell's law to find the relative index of refraction between the two regions (2) (b) find the wavelength in each region

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
