Answer:

About 8 kpc

Explanation:

The milky way galaxy is the galaxy we live in. Its composed of the solar system, billion stars, gas, dust and dark matter.

At its center it contains a super massive black hole called Sagittarius. This object is millions of times as massive as the sun.

The sun is about 8 kpc to the center of the milky way galaxy, this is about 26,000 light years away.

1000 parsecs distance is approximately 3262 light years.

A light year is the distance light can travel in a period of 1 year.

You are approaching a police car at 68. 1 mph and the police car is approaching you at 94. 8 mph. Assume that the speed of sound

Veronika [31]

We will hear the sound of siren of frequency 1553.4606 Hz.

<h3>What is Doppler Effect?</h3>

The apparent change in wave frequency brought on by the movement of a wave source is known as the Doppler effect. When the wave source is coming closer and when it is moving away, the perceived frequency changes. The Doppler effect explains why we hear a passing siren's sound changing in pitch.

according to Dopplers Effect,

$f'=[\frac{v + v_{0} }{v - v_{s} } ]f$

$f'= [\frac{700+68.1}{700-94.8} ]* 1224$

$f'= 1553.4606 Hz$

the frequency would be 1553.4606 Hz.
