Answer:190.78 km

Explanation:

Given

First Displacement is 100 km ^{\circ}west of north

Position Vector (r_1)of displacement is given by

\vec{r_1}=100cos10\hat{j}-100sin10\hat{i}

\vec{r_1}=98.48\hat{j}-17.36\hat{i}

Considering East as X axis and North Y axis

second displacement is 120 km 50^{\circ} east of north

Now position Vector of second Position w.r.t to first

\vec{r_{21}}=120cos50\hat{j}+120sin50\hat{i}

\vec{r_{21}}=77.13\hat{j}+91.92\hat{i}

\vec{r_2}=\vec{r_1}+\vec{r_{21}}

\vec{r_2}=98.48\hat{j}-17.36\hat{i}+77.13\hat{j}+91.92\hat{i}

\vec{r_2}=74.56\hat{i}+175.61\hat{j}

magnitude of displacement

|r_2|=190.78 km

The availability Heuristics

Explanation:

We make decisions and judgments every day. The heuristic is a mental shortcut that helps us in making the decision and judgment quickly without having spent a lot of time searching or analyzing the facts.  

<u>Availability Heuristic: </u>

Firstly it tells about how quickly we make the decision and judgment and how easily something gets into the mind. We always rely on how easily we can think of an example when we making any decision or judgment.  

The problem with availability heuristic is that we assume that if we get all examples, readily available in our mind, the event or the subject matters is a commonplace.  

However, there are many situations in which availability heuristics is accurate and useful.
