Sound is detected when a sound wave causes the eardrum to vibrate. Typically, the diameter of the eardrum is about 8.4 mm in humans. When someone speaks to you in a normal tone of voice, the sound intensity at your ear is approximately 1.0×10−6W/m2.

How much energy is delivered to your eardrum each second?

= 5.54 × 10⁻¹¹J/s

Explanation:

I = P / A

A = πr²

r = 8.4mm/2

 = 4.2mm

 = 4.2 × 10⁻³m

A = 3.143 × (4.2 × 10⁻³m)²

= 55.4425 × 10 ⁻³m²

P = A× I

  = (55.4425 × 10 ⁻³) (1.0×10⁻⁶)

  = 5.54 × 10 ⁻¹¹ J/s

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

probably not if net force is zero
