The ion has a charge of 1 +.
A neutral ion would have the same number of protons and neutrons. The neutrons have no charge (they're neutral) so they don't matter when it comes to the charge of an ion. This ion has 30 protons (+) and 29 electrons (-). There is 1 more proton than there are electrons so the ion has a charge of 1 +.
Answer:
B. Chemical energy to electric energy to kinetic energy to sound energy
Explanation:
A battery is a device that converts chemical energy, stored in the chemical substance contained inside the battery, into electric energy, by pushing electrons along the circuit at which the battery is connected.
In an MP3 player, this electron (which form an electric current) pass through a sound transducer, which is a device that converts the electric energy of the current into kinetic energy, by producing the vibrations of the loudspeaker (or of the headphones).
As a result, the air surrounding the loudspeakers/headphones start to vibrate, producing sound waves, and the sound that we hear: in this last stage, therefore, kinetic energy has been converted into sound energy.

<span>A partially movable joint is a joint
in which its movement is limited to a certain amount. They are usually supported
by a layer of cartilages and fibrous connective tissues. They are also called
amphiarthrosis joints. Example of this are the joints formed by adjacent
vertebrae containing intervertebral disc of a cartilage. When the joints are
moved, it limits its movement because of
this arrangement. Other examples of this are the ribs and the sternum. Notice that
you cannot twist your upper body at 360 degrees without moving your lower body.</span>
Because its a vacuum, there's no air resistance, they will fall at same time
Applying gravity acceleration rule g=9.8m/s which is taken as 10m/s sometimes.
