How much energy must be absorbed by water with a mass of 0.5 kg
in order to raise the temperature from 30 °C to 65 °C. (Note: Water
has a specific heat of 4,190 J/kg°C.)

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

the total distance traveled by the car is

30km + 49km = 79 km .

i think the answer is a, hope this : )
