Putting Value of X and Y , in LHS we get,

 

→ (2/x+y)² + (x-y/2)²

 

→ (2/secA + sinA + secA - sinA)² + (secA + sinA - (secA - sinA)/2)²

 

→ (2/2secA)² + (secA + sinA - secA + sinA)/2)²

 

→ 1/sec²A + (2sinA/2)²

 

[using 1/secA = cosA ]

 

→ cos²A + sin²A

 

[ Now , we know that, cos²A + sin²A = 1 ]

 

Hence,

 

→ 1 = RHS ( Proved )

● It provides jobs for the locals. Hotels, bars, transport, shops, and restaurants all need staffing. Tourism can provide much-needed employment for people.
● It raises the profile of the place generally. Tourism gives the locality a chance to show itself off and raise its profile in the world.

Advantages of roadways over railways are: 

(i) Construction cost of roads is much lower than railway lines. 

(ii) Roads can be constructed easily in hilly terrains and undulating topography. 

(iii) Roadways act as a feeder to other modes of transport, as they provide a link between railway stations, air and sea ports.

(iv) Road transport is economical in transportation of few persons and relatively smaller amount of goods over short distances.

1. The government provided subsidies to farmers on fertilisers and electricity. However, it led to the use of a large amount of fertilisers and water which resulted in the depletion of essential minerals in the soil and water logging.

2. Due to the minimum support price at which the government purchases food grains and subsidises them, wheat and rice are being grown more by some states. This has disturbed the cropping pattern.

3. Sometimes, people below the poverty line (BPL) have been excluded from the categories, while people above the poverty line (APL) are included in the category even when one of their crops fails.

4. Absence of agricultural infrastructure and linking of the failure to use the latest techniques such as linking credit directly to the bank account of farmers have hampered the food security policy of the government.

The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus . The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.

Cerebrum:The cerebrum is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.

  • Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving
  • Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli
  • Occipital Lobe- associated with visual processing
  • Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech

Thalamus-It is a large mass of gray matter deeply situated in the forebrain at the topmost portion of the diencephalon. The structure has sensory and motor functions. Almost all sensory information enters this structure where neurons send that information to the overlying cortex.

Hypothalamus-It is a part of the diencephalon, ventral to the thalamus. The structure is involved in functions including homeostasis, emotion, thirst, hunger, circadian rhythms, and control of the autonomic nervous system. It also controls the pituitary.

Midbrain-It is involved in functions such as vision, hearing, eyemovement, and body movement.

Cerebellum - The cerebellum has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.

Pons- It is involved in motor control and sensory analysis. It has parts that are important for the level of consciousness and for sleep.

Medulla Oblongata-This structure is present between the pons and spinal cord. It is responsible for maintaining vital body functions, such as breathing and heartrate.

The Raman effect involves scattering of light by molecules of solids, liquids or gases. The Raman effect consists of the appearance of extra spectral lines near the wavelength of incident light. The Raman lines in the scattered light are weaker than the light at the original wavelength. I hope this may help for u☺
