Answer:
Andromeda galaxy is the correct answer.
Answer:
Applied pressure is 1.08 10⁵ Pa
Explanation:
This exercise is a direct application of Boyle's law, which is the application of the state equation for the case of constant temperature.
PV = nR T
If T is constant, we write the expression for any two points
Po Vo = p1V1
From the statement the initial pressure is the atmospheric pressure 1.01 10⁵ Pa, so we clear and calculate
1 Pa = 1 N / m2
P1 = Po Vo / V1
P1 = 1.01 10⁵ 20/18.7
P1 = 1.08 10⁵ Pa
Answer:
Sound Intensity at microphone's position is 
The amount of energy impinging on the microphone is 
Solution:
As per the question:
Emitted Sound Power, 
Area of the microphone, 
Distance of microphone from the speaker, d = 52.0 m
Now, the intensity of sound, 
at a distance away from the souce of sound follows law of inverse square and is given as:
Now, the amount of sound energy impinging on the microphone is calculated as:
If be the Incident Energy/
Then
The amount of energy incident per 1.00 
is:
Cold temperature can't "flow" into a warmer object, in this case, the person's hand. The heat energy of the hand gets transferred to the colder object, the ice.
