Sally started at the starting point.
She walked 10m forward. So far, she walked 10m, and she was 10m from the starting point.
Then she walked 5m backward. So far, she walked 15m, but she was only 5m from the starting point.
The distance she walked was 15m. But her displacement is how far she is from the starting point ... that's only 5m
Displacement = 5 meters
Distance = 15 meters
Displacement is 10m less than distance walked. <em>(B)</em>
===> If she kept going and walked <u><em>another </em></u>5m backward, she would be back where she started. The total distance she walked would be 20m, and her displacement would be zero !

Two methods of transfer of heat are involved in this process: conduction and convection.
In fact, the metal spoon is heated by conduction because the molecules of the boiling water collide with the molecules of the spoon, releasing heat to it; and also by convection, because in the pot of boiling water masses of hot water goes upward and they give their heat to the spoon, then these masses become cooler and they go down, replaced by other masses of hot water.
Conservation is a method of improving air quality
