If the sound comes from the right side, the waves reach the right ear before the left ear. if the sound comes from the left side, the waves reach the left ear before the right ear. The difference between the phases of waves reaching both ears is detected by the ears and then interpreted by the brain
Answer:
what is the question please?
Answer:
(a). The initial pressure is
(b). The final pressure is 
Explanation:
Given that,
Number of moles = 7
Temperature = 475 K
Initial volume = 0.50 m³
Expanded volume = 1.50 m³
We need to calculate the initial pressure
Using formula of pressure

Put the value into the formula


We need to calculate the final pressure
Using formula of pressure

After expansion,


Put the value into the formula
For thermal process,




Hence, (a). The initial pressure is
(b). The final pressure is 
It's true
work measure by joule.
Energy = work/time
= joule/s .
and joule/s represents watt
It slows down. The molecules/particles aren't as close together, resulting in slower movement.
