If there is a net force acting on an object, then newton’s laws predict that:

a. the object will accelerate

b. nothing about the motion of the object will change

c. the motion of the object will slow down

d. the net force will cause the object to stop moving

The correct answer is Option A.

Explanation:

There are two types of forces in accordance to the net force acting on an object:

1. Balanced Forces: When two forces acting on an object has same magnitude and are acting in the opposite direction have net force to be 0. The two forces cancel each other.

2. Unbalanced forces:  When two forces acting on an object has different and are acting in the opposite direction have net force not equal to 0. The two forces will not cancel each other and will accelerate the object. The equation for the unbalanced force is given by:

where, f = net force

m = mass of the object

a = acceleration of the object

Hence, the correct answer is Option A.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
