What change in the sound do you expect to hear when you increase the amplitude of

Engineering

denpristay [2]3 years ago
5 0

Answer:

1. The sound becomes louder by increasing its amplitude

2. The pitch of sound increases by increasing its frequency.

Explanation:

Q1.

The characteristic of sound, which is related to the amplitude of sound wave is <u>Loudness</u>. The amplitude of a wave is associated to the energy carried by it. Therefore, when the amplitude of sound is increased, it increases its energy and thus, we hear a louder sound.

Q2.

The characteristic of sound associated with the frequency of wave is the <u>Pitch</u>. When the frequency of sound wave is increased, its wavelength decrease and the sound is heard at a faster speed. This causes the pitch of sound to get high. And as a result we listen a shrill sound. Therefore, by increasing the frequency of sound, the pitch of sound is increased and a shrill sound is heard.

A 50 Ibm block is moving at 4 ft/s. Find Its total kinetic energy? Also find Its kinetic energy per unit mass is
Kamila [148]

Answer:

Total kinetic energy= 400 puondal foot

Kinetic energy per unit mass= 8 (poundaul foot/lb)

Explanation:

To determine the total kinetic energy of the block we use the equation:

Kinetic energy = (1/2) × m × (v^{2}) = (1/2) × (50lb) × (4 foot/s)^{2}) =

= 400 poundal foot

To establish the kinetic energy per unit of mass we must simply divide the value of the total kinetic energy obtained previously by the mass of the block obtaining:

Kinetic energy per unit mass= (400 poundal foot) / (50lb) =

= 8 (poundaul foot/lb)

A 600 MW coal-fired power plant has an overall thermal efficiency of 38%. It is burning coal that has a heating value of 12,000
velikii [3]

Answer:

See step by step explanations for answer.

Explanation:

600 megawatts =

568 690.272 btu / second

thermal eficiency=work done/Heat supllied

0.38=568690.272/Heat supplied

Heat supplied=1496553.35btu /s

heat emmitted to the atmosphere=heat supplied -work done=(1496553.35-568690.272)=927863.1 btu/s

feed rate=(1496553.35)/12000=124.71 lb/s =10775184.1056 lb/day=5 387.472 ton / day

sulphur content released=(0.03*124.71)/(1.496553)=2.5 lb SO2/million Btu of heat input

so

the degree (%) of sulfur dioxide control needed to meet an emission standard=(2.5/0.15)*100=1666.67 %

the CO2 emission rate=220*(1.496553) =329.241 lb/s =12 903.0802 metric ton / day
