Step 1: Scene Planning and Layout
The street food festival is visualized in a busy urban street with multiple food stalls arranged on both sides. The central pathway is occupied by people standing in queues, walking, and interacting, creating a dynamic composition.
Step 2: Detailing Elements
The sketch includes food stalls with signboards, chefs cooking on stoves, smoke rising from pans, and counters displaying different cuisines. Seating arrangements such as benches and small tables are added to enhance realism.
Step 3: Human Activity and Movement
People are drawn in varied postures—waiting in line, ordering food, sitting, and eating—to capture the lively atmosphere. Facial expressions and gestures add vibrancy and diversity to the scene.
Step 4: Light, Colour, and Texture
Bright and festive colours like reds, yellows, blues, and greens are used for stalls and decorations. Warm lighting from bulbs and lamps highlights food counters, while shadows under stalls and people add depth. Textures of cloth canopies, food items, and pavement are carefully illustrated.
Step 5: Final Presentation
The completed artwork reflects energy, cultural diversity, and urban vibrancy, effectively portraying the spirit of a street food festival through colour, composition, and detail.
In the following \(p\text{–}V\) diagram, the equation of state along the curved path is given by \[ (V-2)^2 = 4ap, \] where \(a\) is a constant. The total work done in the closed path is: 
Let \( ABC \) be a triangle. Consider four points \( p_1, p_2, p_3, p_4 \) on the side \( AB \), five points \( p_5, p_6, p_7, p_8, p_9 \) on the side \( BC \), and four points \( p_{10}, p_{11}, p_{12}, p_{13} \) on the side \( AC \). None of these points is a vertex of the triangle \( ABC \). Then the total number of pentagons that can be formed by taking all the vertices from the points \( p_1, p_2, \ldots, p_{13} \) is ___________.
Consider the following two reactions A and B:
