It is useful to use a model in order to demonstrate how an electric circuit works.
<h3>What is a model?</h3>
In science, a model is a graphical representation that my result useful to predict the behavior of the components of a given system that works together to produce a particular outcome.
For example, an electrical circuit can be modeled by taking into account resistance, voltage, and intensity as parameters of functioning.
The electrical circuits are graphically represented by modeling the movement or flow of negatively charged electrons (e-) from the negative pole to the positive pole of a closed electric circuit.
In conclusion, it is useful to use a model (ie., a scientific model) to demonstrate how an electric circuit works.

Answer:
v= - 4.507 i - 2.363 j
Explanation:
Given that
mc= 1490 kg
vc= 9.5 m/s ( - i)
mt= 1650 kg
vt = 6.4 m/s ( -j)
There is any external force so linear momentum will remain conserve.
Lets take final speed is v.
mc .vc + mt . vt = ( mc+mt) v
1490 x 9.5 ( - i) + 1650 x 6.4 ( -j) = ( 1490+1650) v
14,155 ( -i) + 10,560 ( - j) = 3140 v
v= - 4.507 i - 2.363 j
A=f/m
A=900/425
A=2.18
To determine acceleration you divide the force by the mass.
For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport. They move the same direction as the wave.
