"Silver" is the best electric conductor.
But as it is quite expensive, we use "Copper" & "Aluminium" for that purposes
Hope this helps!
Ok first of all we have to convert in km/hr=Speed
So 30min are 0.5hours
Then we use S= distance/time = 5km/0.5 hrs = 10km/hr —> Jill speed
Then S= d/t = 10km/0.5hrs = 20km/hr —> Scott speed
So Scott rode faster
The reason the large jet was seen, but wasn't heard till a few seconds afterwards, is solely because of the speed of light, rather than sound. We know that light is very, very fast. It's faster than sound! That means that answer choices A, B, and D have been eliminated. You now get:
C) The speed of light is faster than the speed of sound.
Answer:
temper; hot sauce

The 4th definition of temper (as a verb) is "to bring to a suitable state by mixing or adding a usually liquid ingredient." Knowning, this leads to the second blank being <em>hot sauce</em>, as that's a liquid.
