Answer:
A.3.64 m
Explanation:
Because
- v=(fλ)
- (1382)=(380)λ
- λ=3.637m~3.64m
<em>where</em><em> </em><em>,</em><em>v</em><em>=</em><em>velocity</em>
<em>f</em><em>=</em><em>frequency</em><em> </em>
<em>λ</em><em>=</em><em>wave</em><em> </em><em>length</em><em> </em>
The correct answer should be kinetic molecular velocity. Which is a
complex term for the speed of molecules. The faster the molecules move
the more liquid the chemical will be, with the fastest being gaseous
molecules. The slowest ones are things that are solid. This is easily
observed on water that is slowest when ice and fastest when water vapor.
Answer:
Gases - Water vapor, Nitrogen, Oxygen etc. Describe what happens to air pressure as you rise upwards in the atmosphere. What causes this change in air pressure? As altitude increases, air pressure will decrease As altitude increases the gas molecules that make up the air spread further apart
Since both the speeder and the state trooper are moving at the same
speed and same direction, therefore there would be no or zero Doppler shift.
In order to have a Doppler shift, the distance or separation between the
state trooper and the speeder must also be changing with time. Which in this
case, the distance remains the same or constant since they are moving alike.
This is just like what would occur if they were both standing still or parked.
<span>So this further means that the frequency of sound is the same as the
frequency heard by the speeder. Therefore the Doppler "shift" of the
frequency on the speeder would be
<u>zero. </u></span>
