Imagine that you’re observing a collision. which action would allow you to determine whether the collision is inelastic?

measure the force of impact.
observe whether the colliding objects change their shape.
measure the acceleration of the colliding objects.
measure the mass of the colliding objects.

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.
