Agirl carried a box of books up two flights of stairs to her attic. her father carried a box the same weight up a ladder directly to the attic. the girl says she did more work on the box than her father because she walked further up the stairs, is she correct?

The girl is correct because her father only went the distance of the ladder, whereas she went to the extension of two flights of stairs.

Explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

idk im sorry.
