Two men pull a 31-kg box with forces 9.7 N and 7.6N in the directions shown below. Find the resultant acceleration of the box and the direction in which the box moves.

Explanation:

Given that,

Mass of the box, m = 31 kg

The two forces are shown in the attached figure. They are acting in opposite direction.

Net force, F = 9.7 - 7.6 = 2.1 N

The formula for net force is given by :

F = ma

a is resultant acceleration

So, the resultant acceleration is .

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
