When is a stone tied to a string and whirled is most likely to break and why?

If you allow the string to wrap around the finger, as the radius diminishes, the force on the string increases , according to :
>
force = mass (of stone) * (velocity2 / radius)
(assuming the velocity remains constant)

Why A stone tied at the end of a string is whirled in a circle If the string breaks the stone flies away in tangential direction?
As force acting in a circular path is always tangential to the path
What is the manifestation of centripetal force in a stone tied to a string and whirled horizontally?
The circular path that the stone follows is. It takes centripetal force to move any mass in a circular path.
A 20 gram stone is tied to string 50 meter long is being whirled in a circle with a speed of 36 Kilometer per hour find the tension in string?
Convert the speed to meters per second. Use the formula acceleration = speed squared / radius to find the centripetal acceleration. Then use the formula force = mass x acceleration to find the corresponding force.
What is the action and reaction in case of a stone suspended by a string?
Downward force on the stone ===> force of gravity. Upward force on the stone ===> tension in the string. Downward force is equal to the upward force. Total (net) force on the stone is zero. Acceleration of the stone is zero. It just hangs there.
Why does mud attached with the wheel of a vehicle sprinkled away more if its speed increases?
An object moving in a straight line needs to have a force applied to it for it to change direction. A faster object requires a stronger force to change its direction by the same amount in the same amount of space as you did with the lower speed object. Imagine swinging a stone on the end of a piece of string around your head. The stone is moving in a circular motion and therefore it is always changing direction. The string is pulling the stone in a circular motion and is therefore acting as a force. Now the string can only take so much force so if you speed up the stone, the string has to apply more force to the stone in order for it to be changing direction all the time. Once the stone is going fast enough, the string will not be able to provide enough force and will break and the stone will fly off at a tangent. Think of the "stickiness" of the bits of mud as the string. As you speed up the wheel, the string (stickiness) breaks because it cannot provide enough force to keep the mud moving in a circle. If you're interested in this kind of stuff you should study mathematics which covers circular motion in the mechanics section
How is the stone axe fixed to the wooden head?
String or vine, it depends where.
What did the vikings call magnets?
As a compass. They dangled the metallic stone from a string, knowing it would point north.
How would the planet move if the sun suddenly disappeared?
The 'pull' of the sun makes the Earth go around it. It can be compared with you holding a string with a piece of stone attatched to the end. If you start 'moving' the stone (as the Earth does) the movement will take the form of the stone speeding in a circle. That is caused by you exercising - through the string - a gravity-like 'pull' on the stone. If the sun suddenly would disappear, the same thing would happen as when you, spinning the stone around on your string, would suddenly 'disappear' and so let go of the string. The stone then would fly away in a straight line in the direction it was going when you released the string. In the same manner, the Earth would immediately stop speeding around in a circle and fly off in a straight line.
Is sand stone easy to break?
No.
What happens when you tie a stone to a string and whirl it?
When we tie a stone to a string and whirl it, it moves in a circular path.If the velocity becomes too high then the stone changes to a mass of electrons.It starts radiating energy and ultimately falls in our hand.the energy emitted by the stone is given by E = hv.Where h is Plancks constant and v is the radial velocity of the stone.
What were some problems with hunting in the old stone age?
The stone can break. By the way the stone age is not old.
Where can you find cobbel stone in minecraft?
Mostly in dungeons and mined after you break stone!
