Zorluk: OrtaPhysics Fundamentals and Everyday Applications

Match the everyday physical applications in List-I with their underlying physics principles in List-II, and identify the correct set of matching pairs.

  • Working of hydraulic brakes in automobilesPascal's Law of equal pressure transmission in enclosed fluids
  • Brilliant sparkling of a professionally cut diamondTotal internal reflection of light at multiple internal boundaries
  • Melting of a safety fuse wire during an electrical overloadJoule heating effect caused by electric current passing through a resistance
  • Apparent loss of weight of a stone submerged in waterArchimedes' principle of buoyant force exerted by a displaced fluid

Cevap

The correct matching pairs connect: Hydraulic brakes with Pascal's Law; Brilliant sparkling of a diamond with Total internal reflection; Melting of a safety fuse with Joule heating effect; and Apparent loss of weight of a submerged stone with Archimedes' principle.
Each item in List-I correctly pairs with its foundational governing principle in List-II: hydraulic brakes rely on Pascal's law of fluid pressure; the brilliance of diamonds stems from total internal reflection; safety fuse wires function through Joule heating; and the buoyancy of submerged objects follows Archimedes' principle.

Adım Adım Çözüm

1
Analyze the principle behind hydraulic brakes in vehicles.
Hydraulic systems use incompressible fluids to transmit fluid pressure undiminished to brake shoes.
This direct application of fluid statics corresponds to Pascal's Law.
2
Examine the optical mechanism causing a diamond to shine brilliantly.
Light entering the diamond strikes inner faces at angles greater than the critical angle, trapping light through repeated internal reflection.
This matches total internal reflection.
3
Evaluate the thermal effect of electric current in a safety fuse wire.
Excess current generates heat proportional to current squared (I2I^2), raising the wire's temperature to its melting point.
This describes the Joule heating effect of electric current.
4
Determine the principle explaining reduced apparent weight of submerged objects.
Water exerts an upthrust force equal to the weight of displaced water.
This is defined by Archimedes' principle of buoyancy.
