Two boxes are held together by a strong wire and attached to the ceiling of an elevator by a second wire (see diagram to the left). The mass of the top box is 14.2 kg; the mass of the bottom box is 10.4 kg. Assume that the acceleration due to gravity is 9.8 m/ s^2. Find the tension in the top wire (connecting points A and B)

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.
