Answer:

D. Radar uses radio, and the siren uses sound waves.

Explanation:

The main difference between the siren passing by and the radar is that radar uses radio waves and siren uses sound waves.

  • Sound waves are mechanical waves which requires a material medium for their propagation.
  • In a vacuum, the sound waves cannot pass through freely.
  • Radar is an electromagnetic wave.
  • It is particular of radio waves origin.
  • Such waves do not require a material medium for their propagation and hence can be transmitted through a vacuum.

Once formed, how are coordinate covalent bonds different from other covalent bonds?
-Dominant- [34]

Answer:

\boxed {\boxed {\sf {One \ atom \ donates \ both \ electrons \ in \ a \ pair}}}

Explanation:

A covalent bond involves the sharing of electrons to make the atoms more stable, and so they satisfy the Octet Rule (8 valence electrons).

Typically each atom contributes an electron to form an electron pair. This is a single bond. There are also double bonds (two pairs of electrons), triple bonds (three pairs of electrons), and coordinate covalent bonds.

Sometimes, to satisfy the Octet Rule and achieve stability, one atom contributes both of the electrons in an electron pair. This is different from other covalent bonds because usually each of the 2 atoms contributes an electron to make a pair.
