1. The breaking tension of a wire is proportional to its cross-sectional area. It can be determined using the formula: A = (π × d²) / 4 Step 1: Determine the areas First wire (diameter = 1 mm): A₁ = (π × 1²) / 4 = π / 4 Second wire (diameter = 2 mm): A₂ = (π × 2²) / 4 = 4π / 4 = π The area of the seconRead more

    The breaking tension of a wire is proportional to its cross-sectional area. It can be determined using the formula:

    A = (π × d²) / 4

    Step 1: Determine the areas
    First wire (diameter = 1 mm):
    A₁ = (π × 1²) / 4 = π / 4

    Second wire (diameter = 2 mm):
    A₂ = (π × 2²) / 4 = 4π / 4 = π
    The area of the second wire is **4 times** the area of the first wire.

    Step 2: Calculate the breaking tension
    Breaking tension is proportional to the area.

    For the first wire:
    T₁ = 1000 N

    For the second wire:
    T₂ = 4 × T₁ = 4 × 1000 = 4000 N
