a vacume flask dosnt conduct heat ,
space does
a vacume is nessesary to evacuate matter in this dense atmoshere but space is rarefied [sans conductive matter],
on earth we need to empty our the gasses to duplicate the rarified conditions of space ,yet our thermose dosnt conduct heat and space 'vacume ' does.
can space thus be in truth [as a trueism] be called a vacume?

I am having a bit of a hard time with my Chemistry homework. Here's the problem:

Arrange the following in order of decreasing length: meter, mile, centimeter, micron, angstrom, foot, inch, kilometer.

I think the correct order is angstrom, micron, centimeter, inch, foot, meter, kilometer, mile. Is this right? If not, please let me know where I went wrong.

I appreciate your help :)

A hot-air balloonist, rising vertically with a constant velocity of magnitude v= 5.00 m/s, releases a sandbag at an instant when the balloon is a height h= 40.0 m above the ground. After it is released, the sandbag is in free fall. For the questions that follow, take the origin of the coordinate system used for measuring displacements to be at the ground, and upward displacements to be positive.

A: Compute the position of the sandbag at a time 0.400 s after its release.
Take the free fall acceleration to be = 9.80 m/s^2.

B: Compute the velocity of the sandbag at a time 0.400 s after its release.

C: Compute the position of the sandbag at a time 1.35 s after its release.

D: Compute the velocity of the sandbag at a time 1.35 s after its release.

E: How many seconds after its release will the bag strike the ground?

F: With what magnitude of velocity does it strike?

G: What is the greatest height above the ground that the sandbag reaches?

please explain thanks
