Answer:
Isobaric process between points 1 and 2 while isochoric process between 2 and 3.
Explanation:
A themodynamic equilibrium system which changes from initial state to the final state by a process is known as thermodynamic processes. There are many different kinds of thermodynamic process which depends upon the thermodynamic quantities such as pressure, volume, temperature, entropy etc. The most common thermodynamic processes are isobaric, isothermal, isochoric and adiabatic.
When the temperature of the system remains same during the thermodynamic process, the process is known as isothermal.
When the heat of the system remains same during the thermodynamic process, the process is known as adiabatic.
When the volume of the system remains same during the thermodynamic process, the process is known as isochoric.
When the pressure of the system remains same during the thermodynamic process, the process is known as isobaric.
According to the question, between points 1 and 2 pressure remains constant, hence the process is isobaric.
According to the question, between points 2 and 3 volume remains constant, hence the process is isochoric.
Answer:
It happens due to force of friction
Explanation:
If a body is performing a uniform motion and no external unbalanced force appears to apply on it, then the body will come to rest after certain time. The reason behind this is the force of friction that is applied in opposite direction of the motion. So, when there is no apparent unbalanced force it means that the only force acting on the body is the force of friction. This force of friction tends to stop the motion after some period of time, because it is acting in the direction opposite to that of motion.
Hence, the reason behind a body undergoing uniform motion eventually stops is <u>Force of Friction.</u>
Option B makes the most sense. Option A is something you acquire, it wouldn't really cost anything. Utilities usually do not cost more than housing. Savings are subjective, dependent on the person. So option B.

Explanation:
plasma, gas, liquid, solid
Answer:
v_average = 15 m / s
Explanation:
The average speed can be found in two ways,
* taking the distance traveled and divide it by the time spent
* taking the velocities in each time interval and then finding the weighted average by the time fraction
v_average = 1 / t_total ∑ 
vi ti
Let's apply this last equation
Total time is
t = t₁ + t₂
t = 10 + 10 = 20 min
v_average = 10/20 10 + 10/20 20
v_average = 10/2 + 20/2
v_average = 15 m / s
