Explanation

Red light rays have the lowest frequency and highest wavelength value.

Blue or violet light has the shortest wavelength.

Explanation

White goods are considered durable consumption goods.

This means they are goods that are designed to last for a significant period

They are used by consumers for their personal needs

White goods like refrigerators, washing machines, and dishwashers

Explanation

Explanation

Kinetic energy is the energy an object possesses due to its motion.

The faster the object moves, the more kinetic energy it has.

Explanation

Explanation

Magnetic flux linked (Φ) is proportional to the number of turns in the coil.

Doubling the number of turns doubles the total flux linked, assuming the magnetic field and area remain the same.

Explanation

Pressure formula is expressed as P = F/A,

• where P is pressure,
• F is force,
• and A is the area by which the force is applied perpendicularly.

Its SI unit of pressure is Pascal (represented as Pa) 

Definition of Pressure:

 Pressure can be defined as the force acting per unit area.

Explanation

Weight is a vector quantity because it has both magnitude (amount of force) and direction (downward, towards the center of the Earth).

Explanation

The speed of light is much faster than the speed of sound in air.

Light travels 186 thousand miles in 1 second.

While sound takes almost 5 seconds to travel 1 mile.
