st explanation for this?
A) Sound waves can travel from through the air from the station to your radio.

B) Radio stations broadcast from different locations using their own transmitters.

C) Sound of different pitches are used to transmit information from each radio station. These sound waves can travel over land.

D) Waves are used to transmit the radio signal through the air. These waves are encoded at different frequencies for different stations.

D) waves are used to transmit the rail signal though the air. these waves are encoded at different frequencies for different stations

Arlecino [84]3 years ago

Answer:

The correct answer is D.

Explanation:

The radio can pick up several different stations because the waves are used to transmit the radio signal through the air. These waves are coded at different frequencies, assigned to different radios. The waves do not mix, so we can tune several radio stations.    

Have a nice day!

Two cars are moving towards each other and sound emitted by first car with real frequency of 3000 hertz is detected by a person
sertanlavr [38]

Answer:

 v ’= 21.44 m / s

Explanation:

This is a doppler effect exercise that changes the frequency of the sound due to the relative movement of the source and the observer, the expression that describes the phenomenon for body approaching s

           f ’= f (v + v₀) / (v-v_{s})

where it goes is the speed of sound 343 m / s, v_{s} the speed of the source v or the speed of the observer

in this exercise both the source and the observer are moving, we will assume that both have the same speed,

                v₀ = v_{s} = v ’

we substitute

               f ’= f (v + v’) / (v - v ’)

               f ’/ f (v-v’) = v + v ’

               v (f ’/ f -1) = v’ (1 + f ’/ f)

               v ’= (f’ / f-1) / (1 + f ’/ f) v

               v ’= (f’-f) / (f + f’) v

let's calculate

                v ’= (3400 -3000) / (3000 +3400) 343

                v ’= 400/6400 343

                v ’= 21.44 m / s

An area experiences thunderstorms with high winds and a drop in temperature. Which weather event most likely occurred? A. A stat
gavmur [86]

Answer:

C a fast-moving cold front moved through the area.

Explanation:

This is because, since there is a there is a thunderstorm and high winds in the area, this can only be caused by a fast moving front. Also there is a temperature drop, this can only be caused by the fast moving cold front since a cold front has a low temperature.

Thus, for the area to experience thunderstorms with high winds and a drop in temperature, <u>a fast-moving cold front moved through the area.</u>

How can the atomic number of nitrogen be determined?
Doss [256]

Answer:

So... for the element of NITROGEN, you already know that the atomic number tells you the number of electrons. That means there are 7 electrons in a nitrogen atom. Looking at the picture, you can see there are two electrons in shell one and five in shell two.

A soccer ball moving with an initial speed of 1.8 m/s is kicked with a
vova2212 [387]

Answer:

7.0 m

Explanation:

Step 1: Given data

Initial speed of the ball (u): 1.8 m/s

Acceleration (a): 6.1 m/s²

Final speed of the ball (v): 9.4 m/s

Step 2: Calculate the displacement (s) of the ball

The ball is moving with a uniformly accelerated rectilinear motion. We can calculate the displacement using the following suvat equation.

v² = u² + 2 × a × s

s = (v² - u²)/2 × a

s = [(9.4 m/s)² - (1.8 m/s)²]/2 × 6.1 m/s²

s = 7.0 m
