A20 n unbalanced force causes an object to accelerate at 1.5 m/s2. what is the mass of the object?

Force = 20N

acceleration (a) = 1.5 m/s²

Mass of object (m) = ?

From Newtons II law

                       F = m. a N

                        m =  F/a

                        m = 20/1.5

                       m = 13.34 Kg

Mass of an object is 13.34 Kg

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.

i think the answer would be reserve.
