Answer:
The beat frequency is 0.0019 MHz.
Explanation:
Given that,
Velocity = 0.32 m/s
Frequency = 4.40 MHz
Speed of wave = 1540 m/s
We need to calculate the frequency
Case (I),
Observer is moving away from the source
Using Doppler's effect
Where, v' = speed of observer
Put the value into the formula
Case (II),
Cell is as the source of sound of frequency f' and it moving away from the observer.
Using formula of frequency
We need to calculate the beat frequency
Hence, The beat frequency is 0.0019 MHz.
Answer:
coordination
Explanation:
I know because I just took the test and got the answer right.
A spaceship approaches the light at a speed 1.50*10^7m/s which is about 5% of light speed. So the green light will shift towards the blue end of spectrum due to "blue shift."
The frequency should be higher which rules out option B and C. Looking at the magnitude of change, the correct answer should be A.6.08*10^14Hz,
Conduction. Any material that easily allows heat to move through it. Vacuum. A region of space that contains no matter. Solid.
Solar Radiation is just light, or heat, from the sun (solar)
