In an RL circuit (a resistor and an inductor in series) the applied emf is a constant E. R Given that i is the current in the circuit, R the resistance and L the inductance, the equation for the circuit when the switch is closed is; E i ==(1-e-Rt/L) R Write PHP Program to compute the charge q for E = 1000 V, L= 1.0 H, R=100 ohms, t 0.5 s.

C++ You are given the root node of a binary search tree (BST) and a value to insert into the tree. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST.   Example 1: diagram for example 1 attached   Input: root = [4,2,7,1,3], val = 5 Output: [4,2,7,1,3,5] Explanation: Another accepted tree is: Example 2: Input: root = [40,20,60,10,30,50,70], val = 25 Output: [40,20,60,10,30,50,70,null,null,25] Example 3: Input: root = [4,2,7,1,3,null,null,null,null,null,null], val = 5 Output: [4,2,7,1,3,5]   Constraints: The number of nodes in the tree will be in the range [0, 104]. -108 <= Node.val <= 108 All the values Node.val are unique. -108 <= val <= 108 It's guaranteed that val does not exist in the original BST.

Convert Newton's method for approximating square roots in Project 1 to a recursive function named newton . (Hint: The estimate of the square root should be passed as a second argument to the function.) An example of the program input and output is shown below: Enter a positive number or enter/return to quit: 2 The program's estimate is 1.4142135623746899 Python's estimate is 1.4142135623730951 Enter a positive number or enter/return to quit

Python programming  Problem 2. Your friend owns a restuarant. He wants to calculate the tip (15%) and tax (7%) on a meal. He wants you to output the subtotal, tip, tax, and total (on separate lines). Ask the user how much the meal costs
