These 3 questions please. its due in 20 minutes thank you buddy if you answered​

convert five min into sec

=5*60

=300 sec

speed=distance/time taken

=1200m/300s

=4m/s

speed=distance/time taken

5m/s=2000m/time taken

5*time taken=2000m

time taken =2000m/5m/s

time taken =400 sec

convert 3 min to second

=3*60

=120 sec

velocity=120/120

=1m/s

Explanation:

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
