+/*
+Scientists measure an object’s mass in kilograms and its weight in Newtons.
+If you know the amount of mass that an object has, you can calculate its weight, in Newtons, with the following formula:
+
+Weight = Mass x 9.8
+
+Write a program that asks the user to enter an object’s mass, and then calculate its weight.
+If the object weighs more than 1,000 Newtons, display a message indicating that it is too heavy.
+If the object weighs less than 10 Newtons, display a message indicating that the object is too light.
