Heya!!
For calculate aceleration, let's applicate second law of Newton:

⇒ Being:
→ F = Force = 12 N
→ m = Mass = 3 kg
→ a = aceleration = ?
Lets replace according formula and leave the "a" alone:



Result:
The aceleration of the object is of <u>4 m/s²</u>
Bulbs c and b would still be screwed in if they were in to begin with and bulbs A, D, and E. would be unscrewed
The answer would be to research the need. This should have been done before the project began.
False.
Force is found by multiplying mass of an object by its acceleration.
F = mass * acceleration
