Answer: the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.
Explanation: Given that sound at a rock concert power is 130 dB of intensity l2
a whisper power is 2 dB of intensity l1
Using the formula
130dB - 2dB = 10Log(I2/I1)
128/10 = logI2/I1
12.8 = log (I2/I1)
I2/I1 = 6.31 × 10^12
Therefore, the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.
A ripple tank is a shallow glass tank of water used to demonstrate the basic properties of waves. It is a specialized form of a wave tank. The ripple tank is usually illuminated from above, so that the light shines through the water.
Answer:
At constant pressure
Explanation:
Enthalpy of a system may be defined as the system's internal energy in addition to the product of the volume and pressure of the system.
It can be regarded as the system's capacity of heat transfer and to do non- mechanical work.
The enthalpy of the system at constant pressure gives the amount of heat or energy that is either absorbed by the system or released by the system.

i took the assignment thingie and hopefully i’ve helped you luv
To my knowledge, it would be the day.
<em><u>one year: earth </u></em><em><u>revolves around the sun</u></em>
<em><u> one</u></em><em><u> month: moon revolution around the earth</u></em>
<em><u>one</u></em><em><u> day: the earth rotation about its axis</u></em>
However, nothing above indicates what day of the week it is; you can tell when a day has passed, but not what day of the week is.
Hope this helps!
