True. Though typically crack deals take place in a car, or in an alley. The middle of a long block is kind of exposed. It could happen anywhere in Chicago though.
But yeah, criminals structure crime.
1 cubic cm is the same as 1 mL, so the answer would be C.
Answer:
The frequency of sound heard by the boy is 1181 Hz.
Explanation:
Given that,
Frequency of sound from alarm ![f_{0} = 1210\ Hz](https://tex.z-dn.net/?f=f_%7B0%7D%20%3D%201210%5C%20Hz)
Speed = -8.25 m/s
Negative sign show the boy riding away from the car
Speed of sound = 343
We need to calculate the heard frequency
Using formula of frequency
![f = f_{0}(\dfrac{v+v_{0}}{v-v_{s}})](https://tex.z-dn.net/?f=f%20%3D%20f_%7B0%7D%28%5Cdfrac%7Bv%2Bv_%7B0%7D%7D%7Bv-v_%7Bs%7D%7D%29)
Where,
= frequency of source
= speed of observer
= speed of source
= speed of sound
Put the value into the formula
![f=1210\times\dfrac{343+(-8.25)}{343-0}](https://tex.z-dn.net/?f=f%3D1210%5Ctimes%5Cdfrac%7B343%2B%28-8.25%29%7D%7B343-0%7D)
here, source is at rest
![f=1180.8\ Hz](https://tex.z-dn.net/?f=f%3D1180.8%5C%20Hz)
![f=1181\ Hz](https://tex.z-dn.net/?f=f%3D1181%5C%20Hz)
Hence, The frequency of sound heard by the boy is 1181 Hz.
Answer:
induced electromotive force (Voltage) E = - N dΦ / dt
Explanation:
When the magnetic flux this coil induces a current in each turn of the coil, which is why an induced electromotive force (Voltage) appears at the ends of the coil.
This phenomenon is fully explained by Faraday's law
E = - dΦ / dt
where in the case of a coil with N turns of has
E = - N dΦ / dt
Rl flux is the product of the normal to the area by the magnetic field, in this case the flux changes so we can assume that the area of the coil is constant
