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 120-g sample was heated to 92.6°c and placed into a calorimeter containing 82.9 g of water at 20.0°c. the heat capacity of the calorimeter was 15.3 j/k. the final temperature in the calorimeter was 24.8°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.

c=0.213 J/g/K  

Explanation:

Given

sample mass

initial temperature of mineral

mass of water

Water initial temperature

Heat capacity of calorimeter =15.3 J/k

Final Temperature is 24.8

let c be the specific heat of mineral

Heat released by mineral sample=heat absorbed by calorimeter and water

answer: strength i guess

explanation:

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
