Use MultiSim transient analysis to simulate the circuit in the time domain using a sine wave input with an amplitude of 5 V and a frequency of 10 kHz, with capacitor =47 pF and the resistor. From the MultiSim output plot of the input and output waveforms, confirm that this circuit is an integrator.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.

Define thermoplastic polymers and thermosetting polymers in terms of their structures, and (ii) describe briefly a process suitable for the production of products from each type of polymer.
