Mass and weight
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 1000 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.

note: you must use the joptionpane class to read input (input dialog box) and display output (message dialog box). also, remember that the public class and the filename of the source code file must match.

The table in columns a-c contains a list of paint color choices for a bathroom and a laundry room. what is a possible sequence of parameters used to organize the data as shown in columns e-g?

In a cellular network each cell is controlled by a tower what are these towers called?

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
