There is an optimal distance at which space dominoes fall the fastest. When a domino is tipped on it's side, the greater the angle of incline, the greater the acceleration. However, it takes more time for the domino to get to a greater angle of incline.
When the dominoes are closer, the dominoes impact each other at a higher spot, leading to more rotational momentum.
The exact optimal distance, depends various factors including the friction between the dominoes and the floor.

In hot air are particles closer together?
No, farther apart.
Why does sound travel better through wood than it does water?
Exactly what do you mean by "better"? Do you mean farther, faster, louder over the same distance, or something else? Either way, I believe that sound can travel further through most solids than it can through water because the molecules of a solid are packed together much tighter than those of water, meaning that when a sound wave passes through, the molecules of the solid do not have to move as far as those in water to transfer the energy of the sound wave to the next molecule. It is much like dominoes falling. If you stack the dominoes closer together, the same number will fall sooner than dominoes that are stacked further apart. But, it does require more energy to get the dominoes to fall if they are stacked too close, and I think that the same thing applies to sound waves, although I am not sure. But, if the density of the medium (substance the sound is passing through) determines speed of sound travel, then technically sound should travel faster through water than wood, because as everybody knows, (almost) all wood floats, which means that wood is less dense. If it can travel farther through wood, then that might make more sense, seeing as the molecules of wood are stuck in place and less of the energy from the sound wave is wasted by redirecting the movement of a molecule if it wasn't already going in the right direction, as may happen in water. That's my best explanation, but I would advise that you double check somewhere else as well.
The gravitational force between two bodies is F when they are 1 meter apart What will be the gravitational force if they are brought closer so that they are only 0.1 meter apart?
The gravitational force would then be 100F, by manipulating the formula.
What is the distances between compression and rarefaction of longitudinal wave?
Compression is the areas where the particles are closer together. Rarefaction is the areas where the particles are stretched apart.
What are the areas of a sound wave where the molecules in the medium are packed closer together?
Type your answer here... this is called a compression, and when they are spread apart it is called a rarefaction

Are the molecules in your teeth closer together or farther apart than the molecules in your saliva?
The molecules in your teeth are closer together because your teeth is a solid and saliva is a liquid witch is farther apart (has more room)
Do earth and mars get closer every year?
They come closer together, then farther apart, and then closer, with a period of 26 months. The "closest" that Mars ever comes to Earth is about 38 million miles, and the farthest apart is about 240 million miles when we are on opposite sides of the Sun.
