Marina CMI [18]

The result of changing a physical sound wave into an analogous electrical signal using a transducer (such as a microphone) is called analogue audio. In this system, the rapid electrical level is directly proportional to the rapid air pressure taken by the transducer. The analogue signal is then augmented and can be kept on an analogue medium such as tape or transformed further into a succession of discrete mathematical numbers. The advantages of using this device is that it yields a subtle sound and is pleasing to the ear by pushing the signal level and overdriving it. But the disadvantages are editing it would be tedious and prone to degradation.

Bone has a Young’s modulus of about
Softa [21]

Answer:

4.25 mm

Explanation:

σ = E ∙ ∆L/L₀

where σ is stress,

E is Young's modulus,

and ∆L/L₀ is strain (∆L is the deflection, L₀ is the initial length).

Plugging in values:

1.53×10⁸ Pa = (1.8×10¹⁰ Pa) ∆L / (500 mm)

∆L = 4.25 mm

Question 3
GREYUIT [131]

Based on scientific data, the stone is accelerated at approximately 10 m/s^2.

<u>Given the following data:</u>

  • Weight = 5 Newton
  • Height = 44 meters.

<h3>What is gravity?</h3>

Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.

This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.

<h3>Gravity on planet Earth</h3>

Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.

According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 m/s^2.

In this scenario, the stone is accelerated at approximately 10 m/s^2.

Because ions in an ionic crystal are tightly bound together, _____. it takes little energy to change them from a solid to a liqu
umka2103 [35]
Ions are particles formed when an atom of an element looses or gains electrons to attain a stable configuration.They are either positively charged (cations) or negatively charged (anions). Ionic crystals consists of ions bound together by electrostatic attraction forming a regular arrangement, geometric structure called crystal lattice. In an ionic solid the ions are held by strong attractive forces (tightly bound) and cannot move from their positions in the crystal structure and  therefore, do not conduct electricity.

As the temperature rises the solubility of all gases in water also ______
Anastasy [175]

Answer:

As the temperature rises the solubility of all gases in water also will decrease.  

Explanation:

The solubility of gases in water increase with the decrease of the temperature, and vice-versa.  

The scape of the gas molecules from solution occurs by the breaks of the intermolecular bonds as a consequence of the increase of the kinetic energy which causes an increase in the motion of the gas molecules in solution.                                                    

That is why as the temperature rises the solubility of all gases in water also will decrease.      

I hope it helps you!
