The speed of an object only changes if it is acted upon by another force (Newton's first law).
The simple answer is that the object moves at a constant velocity (or remains stationary if it wasn't moving). This is known as Newton's First Law.However, Newton's Laws only apply in what is known as an inertial reference frame. Unfortunately, the definition of an inertial reference frame is a reference frame in which Newton's Laws apply. But, in principle, if you took an object far away from everything, then the simple answer above would, in principle, be correct.
No, the force in tension of a string is not conservative. The only non-conservative force acting is the tension force, but it acts perpendicular to the path of the object at every instant, and so it does zero work.
An objects weight is evenly distributed around its center of gravity or center of mass. Imagine you attach a string to some random point on an object and then let the object hang while holding onto the string. It happens that the center of gravity of the object will always be directly below the point where the string is attached to the object. In fact, this is a good method by which to manually determine the center of gravity of an object. Another way to think about it is this. If you were to apply a force to an object at some random point, in general, not only would the force cause the object to accelerate but the force would also tend to cause the object to rotate. However if you apply the force at the object's center of mass, the object would not tend to rotate in any way, it would only accelerate in the direction of the force.

Newton's First Law of Forces states a lot of things. One of these things are, if an object is in motion, its net-force can not be zero. =================================== Hogwash ! Not only did Newton never make such a statement, it's not even true. When the net force on an object is zero, it continues in constant uniform motion, meaning constant speed in a straight line. If a net force is applied, then the speed or the direction of the object's motion can change ... called "acceleration". When an object is in motion, its momentum and kinetic energy are not zero.
No, Newton's third law applies to any two (or more) interacting bodies.

The speed of an object only changes if it is acted upon by another force (Newton's first law).
String and StringBuilder classes are used to store string values but the difference in them is that String is immutable (read only) by nature, because a value once assigned to a String object cannot be changed after its creation. When the value in the String object is modified, a new object is created, in memory, with a new value assigned to the String object. On the other hand, the StringBuilder class is mutable, as it occupies the same space even if you change the value. The StringBuilder class is more efficient where you have to perform a large amount of string manipulation.
You don't use your index finger on the 5th string as you normally would. You only use your ring finger on the little E (1st)string, and your middle finger on the big E (6th) string. This is a "G" chord with a suspended 2nd.

"An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an external force." -Newton's First LawTo change the direction of an object simply apply an external force to it.
