your 2. A 110 kg man accidentally falls on top of his poor dog with an acceleration of -9.8 m/s2. How much force does this man slam into his dog with?​

Could someone . i have tried to solve myself but my calculation is off

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.

Why do atoms emit energy of only specific wavelengths
