    The decrease in rainfall from east to west in Northern India is due to several reasons. The Himalayas obstruct moisture-laden winds from the Bay of Bengal, causing heavy rainfall on the eastern slopes but blocking moisture on the western side, creating a rain shadow effect. Additionally, regions in the east are closer to the Bay of Bengal and Indian Ocean, receiving more moisture-laden winds. Conversely, areas in the west, farther from these water bodies, experience reduced rainfall, contributing to the east-west rainfall gradient in Northern India.

    Accidentally spilling soapy water on a marble floor would generally make it more challenging to walk on. When soap mixes with water on a marble surface, it creates a thin and slippery layer. This layer reduces the friction between your shoes and the floor, making it slippery and more challenging to maintain stability while walking. The decreased friction causes your shoes to slide more easily across the surface, making walking more difficult and increasing the likelihood of slipping or losing balance.

    Athletes utilize shoes equipped with spikes to enhance their performance across various sports disciplines. These spikes, commonly made from durable materials like metal or sturdy plastic, offer several advantages:

    1. Enhanced Grip and Traction: The protruding spikes embedded in the shoe’s sole offer superior traction by firmly gripping the ground. This is particularly advantageous in sports necessitating rapid changes in direction, swift accelerations, and sudden stops, such as sprinting, football, soccer, and track and field events. They minimize slippage, ensuring stability during dynamic movements.

    2. Performance Improvement: The heightened traction enables athletes to exert more force and power with each step or movement. Sprinters, for instance, benefit from spiked shoes as they aid in propelling off the ground more effectively, thus boosting speed.

    3. Technical Precision: Spikes assist in maintaining proper athletic techniques. Athletes can focus on their form without concerns about slipping, allowing them to perform optimally.

    4. Adaptability to Surfaces: Varied spike lengths and types cater to different surfaces. Longer spikes suit softer or grassy terrains, while shorter ones are ideal for firmer surfaces.

    In essence, spiked shoes deliver superior grip, traction, and steadiness, enabling athletes to attain their highest potential and excel in their respective sports disciplines.

    Seema, pushing the heavier box, will need to apply a larger force compared to Ishant pushing the lighter box. According to Newton’s second law of motion, the force required to accelerate an object is directly proportional to its mass. Therefore, Seema, pushing the heavier box with more mass, will need to exert a greater force to achieve the same acceleration as Iqbal pushing the lighter box.

    The difference between static and sliding friction arises from the interaction of surfaces during motion.

    1. Surface Contact: Static friction involves interlocked irregularities between stationary surfaces, resulting in a larger contact area. When sliding initiates, the contact area decreases, reducing the resistance between surfaces.

    2. Surface Behavior: Initially, static friction causes surface deformation, creating stronger interlocking. As sliding begins, continual deformation lessens, leading to a decrease in resistance.

    3. Energy Transformation: Static friction accumulates potential energy in interlocked surfaces. During sliding, this energy transforms into kinetic energy, reducing the overall frictional force.

    4. Heat and Wear: Static friction generates more heat and wear due to greater force and surface interlocking, whereas sliding friction results in relatively less heat and wear.

    In summary, sliding friction is typically lower than static friction due to reduced contact area, decreased surface deformation, energy transformation, and lesser heat and wear production during motion.
