Yes, a small child can indeed play with a heavier child on a seesaw. This is because reducing the distance from the fulcrum for the heavier child increases the effort required, allowing the smaller child to play without much strain.
Answer:
R₂ / R₁ = D / L
Explanation:
The resistance for a metal can be calculated by
R = ρ L / A
Where ρ indicates the resistivity of aluminum, L is the resistance's length, and A indicates the cross-sectional area
We use this formula for both configurations
For small face measurements (W x W)
The length is
L = W
Area
A = W W = W²
R₁ = ρ W / W² = ρ / W
For larger face measurements (D x L)
Length L = D= 2W
Area A = W L
R₂ = ρ D / WL = ρ 2W / W L = 2 ρ/L
From this, we find the relation to be
R₂ / R₁ = 2W²/L
A.
The absence of a defined volume in gases causes them to disperse throughout the air.
