Yes providing that the line is wide enough and that the can is equally balanced.
A sphere and a cylinder can roll straight.
Yes. If it is not straight, then it is not a line.
it just a straight line
If it is not straight, then it is not a line.
A cone-shaped object will not roll in a straight line because the circumference of the cone changes from one end to the other. For example, if one end of the cone has a circumference of 10 inches, that end will travel 10 inches per revolution, but if the other end of the cone has a 2 inch circumference, it will only travel 2 inches per revolution.
Well, honey, a cone can't roll in a straight line because of its shape. It's like asking a square to roll smoothly without wobbling. Physics just ain't gonna let that happen, sweetie. So, in short, no, a cone can't roll in a straight line.
a cylinder
On a smooth level surface, and with no forces acting on it after the moment of release, it MUST.
A sphere and a cylinder can roll straight.
Yes. If it is not straight, then it is not a line.
Typically, to make the honor roll, students need to achieve a certain grade point average (GPA) which is usually above a C. Most schools require a GPA of 3.5 or higher to qualify for the honor roll. Therefore, it is unlikely that a student with a C grade would be able to make the honor roll unless their school has a different grading system or criteria for the honor roll.
Displacement of a straight line is zero...
A straight line has no vertex.

Every where. Roll a ball on the floor. As soon as it leaves your hand it continues to roll in a straight line. The outside force, friction slows it down. A rock can sit on the ground for a long time until an outside force from someone picks up he rock, or kicks it. Shoot an arrow thru the air. It would continue in a straight line if gravity did not pull it down to earth.
