A stone is tied to one end of string. holding to the other end , the string is whirled in the horizontal plane with progressively increasng speed it breaks at some speed bexause

Breaks because it doesn't have force in the radial direction and thus due to inertia the stones will fly off tangentially.

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.
