Consider a lti system with inputx(t) and outputy(t) described byy(t) =1a(x(t)−x(t−)(a) find the impulse response, h(t), of this system.(b) express the output of this system, y(t), in terms of the inputx(t) asa→0+.(c) find the frequency transfer function, h(jω), of this system. findh(jω)) in the limit asa→0+.note: ez=∑[infinity]n=0znn! and thus lim|z|→0ez= 1 +z.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
