They are both forms of friction. rolling friction occurs because two objects are rubbing against each other. under a microscope you would see that the two objects have bumps and these bumps run into each other, causing both objects to change velocity. thus rolling friction resists the relative motion of two objects. however, static friction occurs when two objects are pressed against each other and they have the same velocity, the microscopic bumps have time to sink in to each otherand creates a better grip than rolling friction. thus static friction resists any relative motion between two objects and is the reason why pushing a car is sudenly easier when it has some motion.
Think of the strings as writing on lines of paper. Paper is a two dimensional surface. The computer array is the equivalent of the two dimensional paper.
No, it is one dimensional. In only has one measurement, length.
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
A two dimensional array is a one-dimensional array of one-dimensional arrays. That is, just as we can have an array of integers, we can also have an array of integer arrays. This idea can be extended such that we can have an array of two-dimensional arrays (a three-dimensional array), and so on. We typically use a two-dimensional array to represent a table of rows and columns, where each row is a one-dimensional array.
The answer is given on the following page.
Only if you have two dimensional objects of specific sizes in specific combinations.
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.
Gravity
Zero. Points are zero dimensional objects. Straight lines are one dimensional objects. Planes and surfaces are two dimensional objects. Volumes and polyhedra are examples of three dimensional objects.
Two-dimensional objects
Gravity
Yes, it's true
A map, painting, or photograph, are all two dimensional representatins of three dimensional objects
s area is on three dimensional objects, but area is on two dimensional objects.
Lines are one-dimensional objects but they can be in 2-dimensional - or even 20-dimensional) space.
