Answer:
Explanation:
R² = F₁² + F₂² + 2F₁F₂ Cosθ , R is resultant force , θ is angle between them
780² = 390² + 550² + 2 x 390 x 550 Cosθ
608400 = 152100 + 302500 + 429000 Cosθ
Cosθ = .3585
θ = 69 degree.
B. An ear squeeze occurs when the pressure inside the middle ear space is less than ambient (surrounding) pressure.
<h3>When external ear squeeze occurs</h3>
External ear squeeze occurs when gas trapped in the external ear canal remains at atmospheric pressure while the external water pressure increases during descent.
Thus, we can conclude that, an ear squeeze occurs when the pressure inside the middle ear space is less than ambient (surrounding) pressure.
