The electric field between two parallel plates has a magnitude of 180 N/C. The two plates are 2.5 cm apart.
Recall that the magnitude of the charge on an electron is
1.602 x 10-19 C.
How much work is done to move an electron from the
positive plate to the negative plate?

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.
