To understand the psychological barriers to communication, we need to explore how mental factors can interfere with the clarity and effectiveness of communication.
Emotional interference occurs when strong emotions, such as anger, fear, or excitement, affect the sender's or receiver's ability to process or respond to messages accurately. For example, if a person is upset, they may misinterpret a neutral message as offensive or be too emotional to communicate effectively.
Prejudices and stereotypes are preconceived notions or biases about certain individuals or groups, which can distort communication. These biases lead to misjudgments and prevent open, unbiased communication. For instance, someone may avoid listening to a person because of their background, appearance, or social status, even before understanding their message.
Lack of attention or focus can hinder effective communication. If a person is distracted or not fully engaged, they may not absorb the message being conveyed, leading to misunderstandings or missed information. This can occur in conversations when individuals are preoccupied with their thoughts, external stimuli, or multitasking.
The three psychological barriers to communication are emotional interference, prejudices and stereotypes, and lack of attention or focus.
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
