Many people know that the weight of an objectvaries on different planets,butdid you know that the wieght of an object on earth also varies according to the elevation oj an object.in particualr ,the weight of an equation follows this equation:w=cr -2 squared, where c is constant and r is the distancethat the object is from the center of the earth. solve the followingA) solve the equation w=cr -2squared.B)suppose that the weight of an object is 100 pds when at seal level. find the value of cthat makes the equation true at 3,963 miles from the center of the earth. C)use the value of cin prior question todetermine how much object would wweigh in death valley(282 ft below sea level). D)the top of mt mckinly at20,320 ft above sea level. Hint;1 mile =5380 ft
