Answer:
Explanation:
Let's start finding the frequency heard by the bystander due to the moving car. We need to use Doppler effect here:
v is the speed of sound (v = 343 m/s)
So, we have:
Now, the beat frequency heard by the bystander is the combine of the frequencies, it means the difference between them. Therefore the equation is given by:

It was important because it tells why the denser material had sunken and the lighter is floating on the surface.
<u>Explanation:</u>
Eventually, after around 500 million years, our young planet's temperature warmed to the liquefying purpose of iron—about 1,538° Celsius (2,800° Fahrenheit). This crucial crossroads in Earth's history is known as the iron fiasco. The iron fiasco permitted more prominent, progressively quick development of Earth's liquid, rough material.
We also know that at one point all the material in the planet was molten because the denser material had sunk and the lighter was floating.
Answer:
<u>receive continuous signals from a ground transmitter</u>
Explanation:
Remember a <u>synchronous orbit is synchronous in the sense that it has equal rotational period to the body orbiting having the same direction of rotation as that body</u>. An example of this is the Moon and the planet earth.
Thus it allows continuous signals to be sent from a ground transmitter and received by a space object.
