The volume will be doubled.
The volume of the cylinder would be doubled.
its volume is also doubled...
The volume is doubled.
If the mass is doubled then the force needed is also doubled,according to the equation F=MV2/R
If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
