Assume you've just parked your 4840 kg car on the side of a road with a 12-degree slope and you want to calculate the forces to make sure it doesn't slide down the hill. assume the static friction coefficient is 0.3 and the kinetic friction coefficient is 0.15. calculate the magnitude of gravity, normal force, and friction force.

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.
