Solve the following activity in pairs . Eldar uses a controller with a circuit to light 16 LED lamps which are labeled from 1 to 16 . When the controller a gives signal to a LED lamp , it changes its state (ON or OFF ) . In the beginning, all the LEDs are swi hed OFF . Eldar has found a sequence of lightning: On the 1st second controller lights ON all LED lamps . ( 1 . 2 ... 3 .) On the 2nd it lights ON the LEDs that are even in the circuit. ( 2 ... 4 ... 6 . ) On 3rd second it lights every third LED in the circuit. ( 3...6...9...) And so it continues in similar way... Which LEDs must be switched ON after the 16th second​

Jennifer has to set up a network in a factory with an environment that has a lot of electrical interference. which cable would she prefer to use? jennifer would prefer to use because its metal sheath reduces interference.

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
