Light travels best through empty space because there is nothing to block/disrupt its path.

There are no choices included with your question, so the space where the list should appear is a vacuum. Vacuum is the environment through which light travels best.

But hey ... When discussing light, what does "best" mean anyway ?

Fastest ? Least absorption ?
Least dispersion ? Least refraction ?
Most direct without bending ?
Least scattering ?

It's OK. Vacuum is the answer for any of those.

Assume your mass is 60 kg. The acceleration due to gravity is 9.8 m/s 2 . How much work against gravity do you do when you climb
Andre45 [30]

Answer:

W=1705.2 J

Explanation:

Given that

mass ,m= 60 kg

Acceleration due to gravity ,g= 9.8 m/s²

Height ,h= 2.9 m

As we know that work done by a force given as

W = F . d

F=force

d=Displacement

W=work done by force

Now by putting the values

F= m g (Acting downward  )

d= h  (Upward)

W= m g h    ( work done against the force)

W= 60 x 9.8 x 2.9 J

W=1705.2 J

Therefore the answer will be 1705.2 J.

If you cannot get a chair to move across the floor, it is because ___ friction opposes your push.
denis-greek [22]
If you cannot get a chair to move across the floor, it is because static friction opposes your push. When you say static or kinetic friction the two object that facing each other are opposing each other. That's why you're having a hard time pushing the chair.
