What is the acceleration of an object with mass of 42.6 kg when an unbalanced force of 112 n is applied to it

Explanation:

To solve this problem we use Newton's second law, which establishes a relationship between mass, acceleration and force applied to an object.

Where  is the force, is the mass and is the acceleration. Because they ask us for acceleration, we clear for  :

And since we have the following information:

and

the acceleration will be:

≈

The answer is that the acceleration of the object is

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

it is b. absorbs thermal energy
