That's true. The only way to stop an object from radiating energy
is to cool it to absolute zero. Since the temperature of space is
roughly 3 degrees above absolute zero, the atoms or molecules
of every object have some kinetic energy, and the object radiates
some heat.
Of course it also absorbs heat at the same time, mostly from the
huge number of stars shining on it.
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.

When temperature decreases the atoms(or molecules) within the substance begin to slow down.
