Answer:
Longitudinal waves travels faster through solids than it does through gases
Explanation:
As we know that longitudinal waves travels through all types of mediums and the speed of longitudinal waves is given as
here we know that
E = elasticity of the medium
= density of the medium
now here we know that elasticity of solids is much more than the elasticity of gases
So the speed of longitudinal waves in solids is more than the speed of waves in gases

Answer:
The gravitational force between m₁ and m₂, is approximately 1.06789 × 10⁻⁶ N
Explanation:
The details of the given masses having gravitational attractive force between them are;
m₁ = 20 kg, r₁ = 10 cm = 0.1 m, m₂ = 50 kg, and r₂ = 15 cm = 0.15 m
The gravitational force between m₁ and m₂ is given by Newton's Law of gravitation as follows;
Where;
F = The gravitational force between m₁ and m₂
G = The universal gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²
r₂ = 0.1 m + 0.15 m = 0.25 m
Therefore, we have;
The gravitational force between m₁ and m₂, F ≈ 1.06789 × 10⁻⁶ N
