Stress is an internal state which can be caused by physical demands on the body (e.g., illness, extreme temperature, exercise, etc) or by environmental and social situations, which are evaluated as potentially harmful, uncontrollable, or exceeding our resources for coping. 

Key PointsKaran is an adolescent, who is having rebellious behavior and always remain isolated from his friends. This scenario is an alarming sign of stress.

Alarming Signs of Suicide

• Unusual show of affection in an otherwise depressed kid
• Noted isolation or withdrawal from friends
• Love failure or break up with a very close friend
• Difficulty in getting along with classmates and rebellious behaviour
• Running away from home, drug or alcohol abuse
• Bullying behaviour and obsession with violence (watching violent scenes in movies)

Hence, we can conclude that the above scenario is reflecting the alarming sign of stress behavioral problems during adolscence.

 Human life completes its journey through various stages, one of the most vital stages in adolescence. Adolescence is the transition period from childhood to adulthood and plays a decisive role in forming prosocial/antisocial adults. All of us undergo this stage, which is full of excitement and poses many challenges.

Key Points  Adolescence is a period of transition when the individual changes- physically and psychologically-from a child to an adult. The period between childhood and adulthood is called adolescence. WHO defined adolescents as people within the age group of 10-19 years. 

• A boy or girl enters adolescence as a child and emerges as a man or woman, expected to be ready to assume an adult role in society.
• The onset of puberty refers to physical changes such as accelerated growth. 
• The period around 10 or 12 years of age is the onset of puberty which usually lasts for 2 years.
• There is a spurt in physical growth and appearance of sex characteristics.
• The first sign of puberty in girls is menstruation and in boys, nocturnal emission (ejaculation of semen during sleep).
• The overall sequence of physical and sexual growth and maturity are comparable for boys and girls, girls attain their adult height, weight, and ability to bear children, two years earlier than boys.

Thus, it is concluded that the onset of puberty refers to physical changes such as accelerated growth. In girls, the growth spurt starts around 10-12 years.

Development describes the growth of humans throughout the lifespan, from conception to death. It refers to development as patterns of change over time. It does not just involve the biological and physical aspects of growth, but also the cognitive and social aspects related to the development. 

Key Points

The important characteristics beliefs of the life span approach are-

• Lifelong development:
  • the potential for development extends across the entire life span, development may involve processes that are not present 13 at birth but emerge throughout the life span. No age period dominates during development.
• Development is Multidimensional:
  • Multidimensionality refers to the fact that development cannot be described by a single criterion such as increases or decreases in a behaviour. It occurs in the biological, cognitive and social-emotional domains.
• Development is Multidirectional:
  • The principle of multidirectional maintains that there is no single, normal path that development must or should take. In other words, healthy developmental outcomes are achieved in a wide variety of ways.
• Development is Plastic:
  • Plasticity refers to the within-person variability which is possible for a particular behaviour or development. For example, infants who have a hemisphere of the brain removed shortly after birth (as a treatment for epilepsy) can recover the functions associated with that hemisphere as the brain reorganises itself and the remaining hemisphere takes over those functions.
• Development is Multidisciplinary:
  • The study of developmental psychology is multidisciplinary. That is, the sources of age-related changes do not lie within the province of any one discipline. For example, psychological methodologies may not be appropriate for understanding factors that are sociological in nature. 

Thus from the above-mentioned points, it is clear that the given statement shows that development is multidimensional.

Psychology is defined as the study that observes and measures mind and behavioural activities.

There are five types of 'psychiatry domain' or psychological domain, viz. biological domain, cognitive domain, development domain, social & personality domain, and mental & physical domain. 
The study of all the five domains is done to conduct research, make assumptions and draw conclusions. 

Key Points

• The mental and physical domain is one of the domains of psychology includes abnormal psychology, health psychology and therapies. 
• This domain has described the myth people are carrying in their minds about mental disorders, mental illnesses, and imbalance.
• As mental illnesses can be diagnosed in the change of someone's mental skills or physical skills or how they perform a specific task, it helps the psychologists in treating them. 
• It not only studies mental skills but also about physical skills as the physical skills of a person also tell a lot about him. Mental processes like how we perceive a concept, how we think, analyze, or take action which has the ability to influence our physical actions or skills we learn.
• The therapies and counselling sessions are not only to treat mental disorders but it is also done to cope with the stress and to live a healthy life. 

Hence, it can be concluded that mental or physical skills are included in the psychiatry domain. 

Additional Information

• Mental skills belong to the cognitive domain of psychology.
• Physical and emotional development belongs to social and personality development that is one of the five domains of psychology.

In triangle ABC,

Therefore, the distance between P and the foot of the tower is 75√3 metres.

8 cm is the answer because DC = EB = 8 cm.

If two parallel lines are cut by a transversal, the corresponding angles are congruent. If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.

Mode is the value with the maximum frequency. Thus, it can be determined from the graph.
Median is the middle value of the data. Thus, it can be determined from the graph.
Mean is the ratio of sum of all data values and the total number of values. Thus, it cannot be determined graphically.
The bell curve or standard deviation graph is used to visualise the spread of data. The standard deviation tells how much the data is clustered around the mean of the data. Lower standard deviation tells that the data is less spread and higher standard deviation tells that data is more spread.

Three digits numbers divisible by 7 are 105, 112, 119,.........., 994
Here, a= 105, d = 112 - 105 = 7, a_n = 994 

We have perimeter=16.4cm
2r+arc=16.4
Arc=16.4-10.4=6cm
Area = ½*r*Arc=½*r*6=3^rd which is three times r so B is the answer.

By subtracting 1 from 2,you will get 1 that makes the whole square of (x+1)=1

Given: p(x) = 3x²−px−2 = 0
∴ p(2) = 3(2)²−p(2)−2 = 0
⇒ 12−2p−2 = 0
⇒ −2p = −10
⇒ p = 5

To find the maximum length of a pencil that can be kept in a rectangular box of dimensions 8 cm × 6 cm × 2 cm, we need to find the length of the diagonal of the box, which will be the maximum length of the pencil that can fit inside the box.Using the Pythagorean theorem, the length of the diagonal of the box can be found as:Diagonal = √(length² + breadth² + height²)
Diagonal = √(8² + 6² + 2²)
Diagonal = √(64 + 36 + 4)
Diagonal = √104
Diagonal = 2√26Therefore, the maximum length of a pencil that can be kept in the rectangular box is 2√26 cm, which corresponds to option C.

Let minimum value be x ,
So,
75 - x = 20
x = 75 - 20
x = 55

Number of outcomes = 2
Number of total outcomes = 3 + 2 + 4 = 9
∴ Required Probability = 2/9
