Scientists measure an objects mass in Kilograms and its weight in newtons. If you know the mass of an object, you can calculate its weight in newtons, with the following formula weight = mass X 9.8 . Design a program using pseudocode and comments that asks the user to enter an objects mass, and then calculates its weight. If the object weighs more than 1000 newtons display a  message indicating that it is too heavy. If the object weighs less than 10 newtons, display a message saying it is to light. Here are some necessary parameters to follow to help solve the problem.a. Create a global constant for the multiplier b. Create a main module. It should declare two local variables and call three other modules c. Create a module to get the input from the software user d. Create a module to calculate the weight e. Create a module to display the answer. //Please write line numbers before each line of the algorithm, include blank numbered lines between modules and write comments
