a security system uses sensors at every door and window which will set off an alarm if any one of them is opened. there is also a keypad by an entry door to turn on or turn off the system. describe how these components can be wired in a combination circuit to provide the needed security.

Answers

Answer 1

Answer: Wire the motion sensors in rooms and in between rooms in a series circuit and connect the sensors on all the doors and windows in a parallel circuit.
The reasoning being, if you open a window or door the sensors will trip and the circuit will break if the sensors are wired in series, however, if the sensors are connected in parallel the sensors can be opened and the alarm system will not stop working. By connecting the stationary sensors in series, you will prevent people from disconnecting these sensors without the alarm going off.

The answer is : It highlights the contrast between the Dursley's excitement for the dinner and Harry's loneliness.

Harry is a lonely boy as he must remain outcast and invisible to Dursley's visitors. During this time, Dursleys are expecting some visitors which has relation to Vernon's job.

Will give brainliest and good amount of points, no false answers.I am using javascript for school and I still have no idea what I am doing. Can someone help? The instructions are, A key step in many sorting algorithms (including selection sort) is swapping the location of two items in an array. Here's a swap function that looks like it might work, but doesn't:-the code prints out [9, 9, 4] when it should print out [9, 7, 4].Fix the swap function.Hint: Work through the code line by line, writing down the values of items in the array after each step. Could you use an extra temporary variable to solve the problem that shows up? Once implemented, uncomment the Program.assertEqual() at the bottom to verify that the test assertion passes.the layout for javascript is,var swap = function(array, firstIndex, secondIndex) {array[firstIndex] = array[secondIndex];array[secondIndex] = array[firstIndex];};var testArray = [7, 9, 4];swap(testArray, 0, 1);println(testArray);//Program.assertEqual(testArray, [9, 7, 4]);
