bona berada di ketinggian 15 m dari tebing pantai dia melemparkan bola basket bermassa 280 gram dengan kecepatan 2,5 m/s. pada pada tempat tersebut percepatan gravitasi sebesar 10 m/s² berapakah besarnya energi kinetik pada saat bola basket berada di ketinggian 10 m dari permukaan tanah​

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

the objects have the same charge is correct.
