The similarity is that they both are types of bonds in molecules.
Ionic bonds are between a metal and a nonmetal.
Covalent bonds are between two nonmetals.
It can be called the 'crest' or the 'peak' of the wave.
<span>Foods cook faster when placed in a pressure cooker.
This is because in the pressure cooker, the pressure on the surface
of the water is greater than the normal atmospheric pressure. Under
those conditions, the boiling temperature of water is increased.
So the food can be heated to a greater temperature than the normal
boiling point of water. That means that the food gets hotter, and it
cooks through and through faster.</span>
You must summarize the Text in your own words. so there is no need for any help. XD
<span>assuming the pitch is 100yards long, the player runs 100yards to the other goal then a further 50 yards back to the 50-yard line. So he/she runs 150yards in 18s
150/18 = 8.33yards per second average speed.
Initial velocity = 0, average velocity =8.33
Vav = (Vinitial+Vfinal)/2
Vav = 4.16m/s</span>
