Most tornadoes probably could not, but a high-end EF4 or EF5 most likely could. Tornadoes of that intensity have been known to lift up very heavy objects including parking bumpers, construction equipment, train cars, and even buildings. One EF5 tornado in Alabama picked up an anchored 800 lb safe and threw it 600 feet. When the safe was found its door had been torn off.
Since a tornado is columnar in nature its center is best defined as the tornado's axis of rotation, which also corresponds with the lowest pressure. The actual height of the midpoint varies with how high up the tornado extends, with stronger tornadoes usually extending further up into the parent storm.
The funnel is usually the same color or close to the same color as the clouds above. In low humidity the tornado may be invisible until it stats lifting dust.
The condensation funnel of a tornado is basically a cloud formed when moisture inside a tornado condenses and in that sense it is similar to an ordinary cloud. The debris cloud of a tornado is a cloud of debris picked up by a tornado usually from buildings and trees the tornado has damaged or destroyed.
The average tornado is about 50 yards wide, but they have been recorded up to 2.5 miles wide (the record).
Tornado
Yes. A strong tornado in the range of EF2 to EF5 can pick up a bus or even a train.
They pick it up from the ground
"I'll pick you up later."
Air in a tornado moves upward rapidly, sometimes taking objects with it.
No. Though a very strong tornado might cause it to collapse.
An EF0 tornado can't pick up much of anything, so probably not.
Yes, a very strong tornado can sweep it off its foundation and reduce it to rubble.
Yes, though it would require a rather strong tornado, probably at least an EF3.
That is extremely difficult to estimate and would depend on the size and strength of the tornado and what there is to pick up. A large, violent tornado moving through a developed area might be carrying many thousands of small objects.
Yes. Tornadoes have been known to lift up airplanes.
Yes. Tornadoes are incredibly powerful.
No. A skyscraper is far to heavy. However, an EF5 tornado may cause a skyscraper to collapse.
