You are asked to perform a queue operation using a stack. Assume the size of the stack is some value ‘n’ and there are ‘m’ number of variables in this stack. The time complexity of performing deQueue operation is (Using only stack operations like push and pop)(Tightly bound).
Which of the following statements regarding Stacks is/are True? i) The stack always grows towards higher addresses ii) The stack always grows towards lower addresses iii) The stack has a fixed size iv) The width of the stack is 32 bits
Pushing an element into stack already having five elements and stack size of 5, then stack becomes ___________
Which of the following array element will return the top-of-the-stack-element for a stack of size N elements(capacity of stack > N)? b) S c) S d) S
Principle: A person is duty bound to act with such reasonable caution as a prudent man would have exercised under such circumstances.
Facts: The defendant 'D', built a hay stack near the boundary of his land which bordered the plaintiffs land. He had been warned several times by many in the vicinity over a period of five weeks that the manner in which he built the hay stack was dangerous. The defendant's hay stack had been built with a precautionary "chimney" to prevent the hay from spontaneously igniting, but one day it caught fire. Consequently, the hay ignited and spread to the plaintiffs land, burning down two of the plaintiffs cottages.
Is 'D' liable?
A Carnot heat engine receives heat at 750 K and rejects the waste heat to the environment at 300 K. The net work output of the heat engine is used to drive a Carnot refrigerator, whose COP is 6.14. If the heat removal rate from the refrigerated space is 6.6 kW, determine the rate of heat supply to the heat engine?
If DC generators are located near load centres, which losses can be minimised?
A 10 cm dia steam pipe, carrying steam at 180°C, is covered with an insulation (conductivity = 0.6 W/m.°C). It losses heat to the surroundings at 30°C. Assume a heat transfer co-efficient of 0.8 W/m2.°C for heat transfer from surface to the surroundings. Neglect wall resistance of the pipe and film resistance of steam. If the insulation thickness is 2 cms, the rate of heat loss from this insulated pipe will be
Fourier's law of heat conduction is (where Q = Amount of heat flow through the body in unit time, A = Surface area of heat flow, taken at right angles to the direction of heat flow, dT = Temperature difference on the two faces of the body, dx = Thickness of the body, through which the heat flows, taken along the direction of heat flow and k = Thermal conductivity of the body)
