A hiker walks 200 m west and then walks 100 m north. In what direction is her resulting displacement?Select one:a.None of the answers is correct.b.northwestc.northd.west

hiker starts at his camp and moves the following distances while exploring his surroundings:75.0 m north, 2.50102 m east, 125 m at an angle 30.0° north of east, and 1.50102 m south.(a) Find his resultant displacement from camp. (Take east as the positive x-direction and north asthe positive y-direction.)

An avid hiker keeps meticulous records of their hikes. During the last hike that took exactly steps, for every step it was noted if it was an uphill, , or a downhill, step. Hikes always start and end at sea level, and each step up or down represents a unit change in altitude. We define the following terms:A mountain is a sequence of consecutive steps above sea level, starting with a step up from sea level and ending with a step down to sea level.A valley is a sequence of consecutive steps below sea level, starting with a step down from sea level and ending with a step up to sea level.Given the sequence of up and down steps during a hike, find and print the number of valleys walked through.Example The hiker first enters a valley units deep. Then they climb out and up onto a mountain units high. Finally, the hiker returns to sea level and ends the hike.Function DescriptionComplete the countingValleys function in the editor below.countingValleys has the following parameter(s):int steps: the number of steps on the hikestring path: a string describing the pathReturnsint: the number of valleys traversedInput FormatThe first line contains an integer , the number of steps in the hike.The second line contains a single string , of characters that describe the path.ConstraintsSample Input8UDDDUDUUSample Output1ExplanationIf we represent _ as sea level, a step up as /, and a step down as \, the hike can be drawn as:_/\ _ \ / \/\/The hiker enters and leaves one valley.
