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 128-g sample was heated to 96.2°c and placed into a calorimeter containing 77.2 g of water at 20.0°c. the heat capacity of the calorimeter was 13.9 j/k. the final temperature in the calorimeter was 23.3°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
