The object will remain at rest
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Here net force is zero
An object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity.
F=MA
Force F=0
Than Acceleration A=0
With zero Acceleration stationary object will remain at rest.
Hence Remain at rest is the correct answer

Neutral reaction is the reaction that occurs when an acid cancels with a base
This is because the earth is way heavier than Jessica hence has a greater force of gravity applied on Jessica that Jessica applies to earth. The distance between the Earth and Jessica is also very short hence the force of gravity on Jessica towards earth is greater. According to Newton's laws that states; if an unbalanced force acts on an object, it will change the object's state of motion (the object will accelerate). The earth cause Jesica to ‘accelerate’ towards the ‘core’ when she stumbles.
The mass and tension due to the system are as follows:
- The mass of the child and scale = 10.6 kg
- The tension T, in the cord attaching the child to the scale = 104N
- The tension T', in the cord attaching the scale to the ceiling T' = 108.9 N
<h3>What is tension?</h3>
Tension is a type of pulling force due transmitted by means of a string or cable.
<h3>Force = mass * acceleration due to gravity</h3>
a) The mass of the child and scale = 104/9.81 = 10.6 kg
b) The tension T, in the cord attaching the child to the scale = scale reading = 104N
c) The tension T', in the cord attaching the scale to the ceiling = scale reading + weight of scale
T' = 104 + (0.5 * 9.81)
T' = 108.9 N
d) The sketch is attached in the picture
In conclusion, the tension is force exerted on the cord due to the weight of the scale and the baby.
