In the circuit shown below what is the output voltage (V_{out}) in Volts if a silicon transistor Q and an ideal opamp are used?

The transfer function V_{2}(s)/ V_{1}(s) of the circuit shown below is

Assuming zero initial condition, the response y (t) of the system given below to a unit step input u (t) is
 The impulse response of a system is h(t) = t u(t) . For an input u(t 1) , the output is
 Which one of the following statements is NOT TRUE for a continuous time causal and stable LTI system?
 Two systems with impulse responses h_{1} (t) and h_{2} (t) are connected in cascade. Then the overall impulse response of the cascaded system is given by
 A source v_{s} (t) = V cos 100 Ï€t has an internal impedance of (4 + j3)â„¦ . If a purely resistive load connected to this source has to extract the maximum power out of the source, its value in â„¦ should be
 A singlephase load is supplied by a singlephase voltage source. If the current flowing from the load to the source is 10âˆ 150^{o}A and if the voltage at the load terminals is 100âˆ 60^{o} V, then the
 A singlephase transformer has noload loss of 64 W, as obtained from an opencircuit test. When a shortcircuit test is performed on it with 90% of the rated currents flowing in its both LV and HV windings, the measured loss is 81 W. The transformer has maximum efficiency when operated at
 The flux density at a point in space is given by B = 4 xa_{x} + 2kya_{y} + 8 a_{z} Wb/m^{2}. The value of constant k must be equal to
