Awave created by a certain source travels from medium 1 into another medium 2. it is noticed that its velocity is faster in medium 2 than in medium 1. three students are discussing what happens to the wave as it moves into medium 2. student 1: frequency increases. student 2: wavelength increases. student 3: both change. which student is right?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
