Dynamic Behaviour of a System

Could you please simulate the dynamic behaviour of the system using matlab and simulink for the mass - spring system? Please refer to the attachment.

Source and load question for train hobby project

Have four circuits. One takes 9Vdc, two 5Vdc, and last one takes 12Vdc. Have variable transformer for source. How do I calculate or choose the voltage needed to run all four circuits with out blowing them all up, and at the same time run each circuit by themselves or two at a time or three, etc. How do I know how much curren

Theveninization of a transisor circuit

Find Icq and Vceq for the circuit when Beta=100. I put the 60k and 30 k resisters in parallel and then did a thevenin equivalence on the parallel combination resistance and the 20k ohm resistor. Then, I did kvl around the b-e loop and got icq=.021ma and vce=.39v. Did I do the thevinin equivalence correctly?

Heating Element

An electric heating element is connected to a 110 v circuit and a current of 3.2 A is flowing through the element. How much energy is used up during a period of 5 hours by the element? (a) 352wh (b) 550wh (c) 1,760wh (d) 2,580wh

Deriving a multilevel circuit

Consider the function in the attached file- the cost of the minimal SOP expression is 14, which includes four gates and 10 inputs to the gates. Use Shannon's expansion to derive a multilevel circuit that has a lower cost and give the cost of your circuit.

Relationship of Logic Expressions

Determine the relationship between the two logic expressions. Please see attached MS Word file for the complete program, in order to answer which of the following relationships is true. A. f= g+x1 B. f= g C. f= g + x2 D. none of the above

Ripple voltage in diode circuit

Determine the capacitance required in a half wave rectifier to produce a ripple voltage less than 0.2V. Assume that the input is a 60Hz signal with maximum voltage VM=100V and the load resistance R= 10kW. I'm confused. What formulas do I use and how do I solve this?
