Design a system called a parallel binary comparator, that compares the 4 – bit binary string A to the 4 – bit binary string B. If the strings are exactly equal, provide a HIGH – level output to drive a warning buzzer.
Write the Boolean logic Equation and draw the logic circuit along with its truth table that represents the following statement:
“A bank burglar alarm (A) is to activate if it is after bank hours (H) and the front door (F) is opened or if it is after banking hours (H) and the vault door is opened (V)”.
A capacitive level sensor has the dimensions and properties shown below. What is the capacitance C in picofarads at the liquid level shown? Type in a one-decimal number
H = 4.0 meters
h = 3.9 meters
a = 1.0 millimeters
b = 6.0 millimeters
ε = 8.8542 x 10 picofarads/meter
k = 78.5
2. Box 1, a wooden box, has a mass of 8.60 kg
and a coefficient of kinetic friction with the
inclined plane of 0.35. Box 2, a cardboard box,
sits on top of box 1. It has a mass of 1.30 kg.
The coefficient of kinetic friction between the
two boxes is 0.45. The two boxes are linked by
a rope which passes over a pulley at the top of
the incline, as shown in the diagram. The inclined plane is at an angle of 38.0° with respect to thehorizontal.
(a) What is the acceleration of each box? (7 marks)
(b) Now consider all surfaces are frictionless. Then calculate the amount of force with direction
to prevent the sliding of the boxes. (3 marks)
Think gravity battery.
- How much suspended weight and how far down would it need to be lowered in order to produce 100kwh?
- How many Kw would it take to lift the weight back up?
- What style of motor/generator can do this? It's being used both as the generator and the motor.
A direct drive AC high torque would be good to keep the RPM's and maintenance low. Any experts on motors here?

Theoretically plan experiments to determine the specific gravity of a solid material sample and a liquid sample other than water. Plan the experiments you will carry out, providing a list of other equipment you would theoretically need for the Laboratory Technician. After you have written out a plan the experiments present your expected findings as a laboratory report listing equipment, method, results, calculations and conclusion. Your report should also include an evaluation of the two methods.
