Suppose you walk 11.2 m straight west and then 27.3 m straight north. How far are you from your starting point

29.51m

Explanation:

Suppose you walk 11.2 m straight west and then 27.3 m straight north. How far are you from your starting point

Your distance from the starting point is your displacement

Using the pythagoras theorem

d² = (-11.2)²+(27.3)²

d² = 125.44+745.29

d² = 870.73

d = √870.73

d = 29.51m

Hence your distance from the starting point is 29.51m

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.
