Answer:
C. The outer ear has to collect the sound waves and lead them to the middle ear.
Explanation:
In the process of hearing, the first thing that happens is that sound waves enter the outer ear through a passage called "auditory canal" that reaches the eardrum.
The movement of the incoming sound waves causes the eardrum to vibrate and transmit these vibrations to three tiny bones of the middle ear.
Answer:
decreases
Explanation:
on each collision, the electrons that make up x-rays get absorbed.
The particles in diagram 3 move fast enough to break away from each other.
According to Charles law, we know, at constant pressure, volume is directly proportional to temperature.
So, <span>V/T = constant
</span>
V₁/t₁ = V₂/t₂
V₁t₂ = V₂t₁
Here, we have: V₁ = 9 mL
V₂ = ?
T₂ = 50+272 = 323 K
T₁ = 19+273 = 292 K
Substitute their values into the expression:
9 × 323 = V₂ × 292
V₂ = 2907 / 292
V₂ = 9.95
After rounding-off to unit place value, it would be equal to 10 mL
So, In short Option C would be your correct answer.
Hope this helps!
Answer:
Explanation:
Given data:
vapor pressure P_1 = 0.6 L
Volume = 2L
Temperature remain constant
No change in vapor pressure. This is because vapor pressure is calculated from the temperature of the liquid and not the volume of the container. Since the temperature is constant therefore vapor pressure remian constant..
