A5 kg object is accelerating at 3 m/s2 while being pulled. What is the magnitude of the force causing this acceleration?

The magnitude of the force causing this acceleration is 15 N

Explanation:

we know that

F=ma: According to the newton's second law

F - force acting on the object

m - mass of the object

a - acceleration

Newton's second law states that acceleration depends on force acting on the object and mass of the object.

Force is directly proportional to acceleration and mass is inversely proportional to acceleration.

here,

m = 5 kg

a = 3 m/s2

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
