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

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
