It is larger than all sorts of things. What you are probably referring to is that it is larger than the planet Mercury.

No, it is not necessarily true that larger things have smaller volume compared to smaller things. The volume of an object is determined by its dimensions and can vary depending on the shape and size of the object. Larger things can have larger volumes than smaller things if their dimensions are proportionally larger.
obtuese
Yes, they have larger braking surface/weight of vehicle, than a car.

The question "Do things with larger masses have larger velocities?", by itself, is meaningless, as you did not provide enough information. Things with larger masses do require more force to accelerate them than things with smaller masses. Things with larger masses do have more kinetic energy than things with smaller masses for the same velocity.

The kinetic energy of a vehicle is directly proportional to its mass and velocity. A larger vehicle will have more kinetic energy than a smaller vehicle traveling at the same velocity. This means that a larger vehicle will require more distance to come to a stop compared to a smaller vehicle, all else being equal.
If it is larger than 16,000 gross vehicle weight, it does.
Because the artery supplying the brain is larger, closer to the heart, and carries more blood than the blood vessels in the wrist.
