I walked my dog 100 meters North to the end of the block, and 50 meters East to the park. After the park, I walked 60 meters South to my friend's house. What is the total distance traveled? Is the displacement of my journey scalar or vector?

The answer is below

Explanation:

Distance is a measurement of how far apart two points are. Distance is a scalar quantity, i.e. it has magnitude and no direction.

Total distance traveled = distance traveled north + distance traveled east + distance traveled south

Total distance traveled = 100 + 50 + 60 = 210 meters

Displacement is the shortest distance between the starting and end points.

displacement² = 50² + (100 - 60)²

displacement² = 2500 + 1600

displacement = 64 meters

The displacement of the journey is vector, because displacement is a vector quantity.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

heat is transmitted by radiation
