When a scale is used to weigh an object on Earth, it measures the gravitational force that pulls on the object. The unit for the force of gravity pulling on an object is the newton (N). A student uses a scale to measure the force of gravity on five different objects. The masses of the objects are 20, 40, 60, 80, and 100 grams. She plotted her data on the graph shown below. What does the data show? A. An object gains mass when the gravitational force on Earth remains the same. B. The greater the mass of an object, the greater the gravitational pull exerted on it by Earth. C. An object loses mass when the gravitational force on Earth remains the same. D. The smaller the mass of an object, the greater the gravitational pull exerted on it by Earth.

Consider this data sequence: "3 11 5 5 5 2 4 6 6 7 3 -8". any value that is the same as the immediately preceding value is considered a consecutive duplicate. in this example, there are three such consecutive duplicates: the 2nd and 3rd 5s and the second 6. note that the last 3 is not a consecutive duplicate because it was preceded by a 7. write some code that uses a loop to read such a sequence of non-negative integers , terminated by a negative number. when the code finishes executing, the number of consecutive duplicates encountered is printed. in this case, 3 would be printed. assume the availability of a variable, stdin, that references a scanner object associated with standard input. that is, stdin = new scanner(system.in); is given.
