You are tasked with designing a lock for a dog door. The door has fouruser settings: (1) The door opensfor any animalthat approaches via a motion sensor; (2) The door opens when dog approaches via a motion sensor and the dog has a proper collar RFID. This will allow only specific dogs in; (3) The door is always locked. This is useful for nighttimeand vacations; (4) The door is always open unless a cat approaches via a camera system. To avoid false positives, the motion sensor must detect an animal approaching and the RFID sensor must be negativeto close. This is an expensive addon for people who paranoid a cat might come in the house. a) Write a simplified statement for the prompt
b) Write a Boolean expression.
c) Draw the circuit diagram
d) If I asked for a truth table, how many rows would it have?

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
