Action Shoes was the first Indian footwear brand to license Disney characters for its children's sandals line. This strategic partnership helped Action compete in the premium kids' footwear segment by leveraging Disney's brand appeal among children and parents.

Adidas was founded in Germany by Adolf Dassler in 1949. The name 'Adidas' is derived from 'Adi Dassler.' Germany remains the company's headquarters, and it's now the world's second-largest sportswear manufacturer after Nike.

Onida's legendary tagline 'Neighbors envy, Owner's pride' captured the aspiration of middle-class Indian consumers in the 1980s-90s. The campaign featured the iconic 'devil' mascot and positioned Onida TVs as premium status symbols worth envying.

The four interlocking rings represent the 1932 merger of four companies: Audi, DKW, Horch, and Wanderer, forming Auto Union AG, which eventually became modern Audi. Mercedes uses a three-pointed star, and the other options are unrelated to this four-ring symbolism.

The SI unit of force is the newton (symbol: N), named after Sir Isaac Newton. One newton is defined as the force required to accelerate a mass of one kilogram at one meter per second squared (1 N = 1 kg·m/s²). Pascal is the SI unit of pressure, not force.

1 horsepower (hp) = 746 watts. This is a standard conversion factor established by James Watt when he developed the concept of horsepower to compare steam engine output to horse power. The exact value is approximately 745.7 watts, but 746 is the commonly used rounded value in calculations.

The equation v = u + at is the first equation of motion in kinematics, where: v = final velocity, u = initial velocity, a = acceleration, and t = time. This equation describes how velocity changes under constant acceleration. The blank must be filled with 'u' (initial velocity).

Inertia has three types: (1) Inertia of rest - tendency to remain at rest, (2) Inertia of motion - tendency to remain in motion, and (3) Inertia of direction - tendency to maintain direction of motion. These are all manifestations of Newton's First Law of Motion (Law of Inertia).

ACID stands for Atomicity, Consistency, Isolation, and Durability - the four key properties that guarantee database transactions are processed reliably. Atomicity ensures all-or-nothing execution, Consistency maintains data validity, Isolation prevents interference between transactions, and Durability ensures committed data persists.
