what would happen to speed if distance increased in the same amount of time?

The speed will be increased.

Explanation:

We can better understand this analysis, if we use numerical values and remember the expression or formula for speed. We know that speed is defined as the distance travelled at a given time.

So if we have the distance x = 4 [m] and the time 2 [s], the speed will be:

v = (4/2) = 2 [m/s]

And if we increase the distance to x = 10 [m] at the same time 2[s], the speed will be:

v = (10/2) = 5 [m/s]

So we can see that the speed is increased.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

the inner core.

good luck: )
