Answer:
is the car's acceleration.
Explanation:
Initial velocity of the driver = u = 14 m/s
Final velocity of the driver = v = 5.5 m/s
Duration of time in which 14 m/s velocity is changed to 5.5 m/s = t = 6.0 s
Acceleration of the driver = a
Using first equation of motion: v = u + at
Negative sign indicates the that is deceleration is occurring that is speed of the car is decreasing.
In aluminium fluoride, aluminium carries positive charges so fluoride should carry negative charge to be electrically neutral.So for aluminium ion with three positive charges fluoride ion should possess three negative charges to make aluminium fluoride electrically neutral.
