The thermal process that occurs when pressure and volume are variable, while the temperature remains constant is known as an isothermal process. Due to the change in temperature being zero, the internal energy of the system does not change. Isothermal processes can be carried out adiabatically or non-adiabatically. (An adiabatic process is where the heat energy moving through the boundary of a system is 0)

Answer:
F - fr = ma
, N - W = 0
Explanation:
In this exercise we are asked to identify the forces that act on the jack, for this we will use Newton's second law
On the x axis
We have two forces: the friction and the force of the girl who pulls the cat
F - fr = ma
On the y axis
There are two forces: normal and weight
N - W = 0
A diagram of these forces can be seen in the attachment
They point towards a negative charge.
They point away from a positive charge.
They never cross.
Answer:
The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length, and the properties of those materials.
