"a hiker starts at point p and walks 2.0 kilometers due east and then 1.4 kilometers due north. the vectors in the diagram below represent these two displacements.

determine the magnitude of the hiker’s resultant displacement."

2.44 km

Explanation:

The resultant displacement of the hiker is just the hypothenuse of the right triangle whose sides are the displacements of 2.0 km east and 1.4 km north. Therefore, the magnitude of the resultant displacement can be found by using Pythagorean's theorem:

he . if i may ask what i your question exactly?

explanation:

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat
