A signal source that is most conveniently represented by its Thévenin equivalent has vs = 10 mV and
Rs
= 1 kΩ. If the source feeds a load resistance RL, find the voltage vo that appears across the load for
RL = 100 kΩ, 10 kΩ, 1 kΩ, and 100 Ω. Also, find the lowest permissible value of RL for which the
output voltage is at least 80% of the source voltage.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.

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