According to meteoric material, the solar system was formed around <u>4.6 billion years</u> ago.
<h3>What substance makes up a meteorite?</h3>
- With just trace levels of sulphide and carbide minerals, they are primarily composed of iron-nickel metal.
- Many asteroids melted during the radioactive element decay in the early solar system, and the iron they carried, being dense, sank to the centre to create a metallic core.

Had to look for the options and here is my answer.
The statement that is considered correct regarding a wave that is propagating along the pavement and girders of a suspension bridge is this: "t<span>he wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions." Hope this helps.</span>
