A girl during a hike has a bottle of mineral water in her haversack. The bottle has 2 litres of water in it (2ltr. weigh 2kg). The water gets heated by the sun by 5 °C. How much heat has the water absorbed from the sun?

Q = 41800[J]

Explanation:

These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.

where:

Q = Heat absorbed [J]

m = mass = 2 [kg]

DT = temperature change = 5 [°C]

Cp = specific heat of the water = 4180 [J/kg*°C]

Units of energy (Joules) [J]

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

true tan speed = ang vel x radius
