Tornadoes of any intensity can merge, however, it would be extremely unusual for two F5 tornadoes to be in such close proximity.
The closest this came to happening in Kansas in 1990. As the Hesston, Kansas tornado was beginning to dissipate the tornado that would later hit Gossel, Kansas was forming. The two tornadoes neared each other and eventually the smaller Hesston tornado, which was in its "rope-out" stage was absorbed into the other, intensifying tornado. Although both tornadoes were ultimately rated F5, neither was at F5 intensity when the two twisters merged.
No, gas particles can touch each other when they collide.
Generally not. When a weather event produces mutliple tornadoes at a time, they are usually far enough apart that they do not interact, so instead they move on more-or-less parallel paths.
When two tornadoes meet, they merge into one tornado.
They cancel each other out
Two molecules must collide with each other.
The warm and the cold air collide violently with each other
If two Tornadoes collide, two things could happen. One, they could whipeout or destroy each other (in other words, stop turning.) Two, they could from an even more destructive torndoes by forming together.
When galaxies "collide", the individual stars do not actually smash together; they're far enough apart that they mostly slip past each other.
because if the planets were close enough to each other to be able to have a gravitational pull strong enough to share rings, the planets would ultimately collide
solids
When two tectonic plates collide with each other. If they collide, they usually slide under each other, causing a tsunami. However, If the collide head on, ground is pushed upward, creating a volcano'mountain
It creates mountians
Yes
armageddon

they hug each other
