Answer:

  • First job out of college was in an industrial manufacturing setting.  Was told by plant engineer to walk around, get used to normal sounds.  He stressed anything "abnormal" is <u>a noise more so than a sound. </u> Report abnormalilies to supervisor immediately!!  So essentially sounds are giving us warnings something is abnormal.
  • Sounds also provide feedback.  Say you are performing an experiment, requires boiling water to sanitize.  Start the burner under a vessel, go on about other preparations.  Sound of water boiling will trigger setting a timer for how long to let it boil.
  • Get off work, pleasant music, nature sounds can help us decompress from a stressful day on the job.

Hope some of these give you impetus to think of other bullet points, sounds good to me.  !!

Vikentia [17]

Answer:

A compressed spring

Explanation:

A compressed spring has potential energy only and no kinetic energy.

This is because kinetic energy is only possessed by particles in motion.

Energy in a compressed spring= -1/2kx² where x is the displacement.

In this equation there is no velocity so there is no kinetic energy.

If a buffer solution is 0.190 m in a weak acid (ka = 8.2 × 10-5) and 0.590 m in its conjugate base, what is the ph?\
Lubov Fominskaja [6]
<span>You use the Henderson - Hasselbalch equation pH = pKa + log ([salt]/[acid]) pKa = -log (8.2*10^-5) = 4.081 pH = 4.081 + (0.590/0.190) pH = 4.081 + log 3.105 pH = 4.081 + 0.49206 pH = 4.573</span>

What is the change in boiling point for a 0.615m solution of Mgl2 in water?
ivanzaharov [21]

Answer :  The change in boiling point is, 0.94^oC

Explanation :

Formula used :

\Delta T_b=i\times K_f\times m

where,

\Delta T_b = change in boiling point = ?

i = Van't Hoff factor = 3 (for MgI₂ electrolyte)

K_f = boiling point constant for water = 0.51^oC/m

m = molality  = 0.615 m

Now put all the given values in this formula, we get

\Delta T_b=3\times (0.51^oC/m)\times 0.615m

\Delta T_b=0.94^oC

Therefore, the change in boiling point is, 0.94^oC
