refractive index of themedium       ? = sin i / sinr

              i = 45 , r = ?

                                                 1.33 = sin 45 / sin?

                                                sin? = sin 45 /1.33

                                                         ? =32.2820     is the angle ofrefraction .

b) from thefigure           tan 45 =    2.1 /  x  

                                     X = 2.1        

                     from which the distance of the person 'x' can bedetermined.

c) if the pool isempty the object must be moved to the distance

                       d = tan(45 -32.282)* depth of the pool.

You must implement the delete method. Below are the requirements: • The delete method takes a Price as an argument and removes the Price from the queue if it is present. (If the Price was not present, the method does nothing). • The method returns true if the Price was deleted and false otherwise. • The method must run in logarithmic time. This is a key requirement. Solutions that are linear or worse will not receive credit. (You may assume...

The programming language is Python Instructions: Create a function that will delete a node in a Linked List based on position number. On below example, if you want to delete position #2, it will remove the Banana (arrangement of nodes below is Apple, Banana, Cherry, Grapes, Orange). myLinkedList = LinkedList() myLinkedList.append("Banana") myLinkedList.append("Cherry") myLinkedList.append("Grapes") myLinkedList.append("Orange") myLinkedList.prepend("Apple") myLinkedList.deleteByPositionNum(2) node = myLinkedList.head while node: print(node.value, " ") node = node.next_node You may start with the function head: def deleteByPositionNum(self, positionNum):
