Atoy car has a mass of 1500g. if a 3-n force is applied to the car, what will it's acceleration be?

F = m * a
F: force = 3N
m: mass = 1500g = 1.5kg
a: acceleration = __ m s⁻²

3 = (1.5) * a
3 / 1.5 = 1.5a / 1.5
a = 3/1.5
a = 2 m s⁻²

Hope this helps! :)

Iam pretty sure its b but if im wrong sorry

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.
