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:
<em>The icicle will be moving at 333.54 m/s</em>
Explanation:
<u>Free Fall Motion
</u>
A free-falling object falls under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not encounter air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is 
.
The final velocity of a free-falling object after a time t is given by:
vf=g.t
The icicle falls from rest for 34 seconds. We need to find the speed after that time:
vf = 9.81*34
vf = 333.54 m/s
The icicle will be moving at 333.54 m/s
Answer:
So, you're going to need the equation ρ = ρo [1 + α(T-To)]
1.59x10^-8 ohms*m is your ρo because that is measured at your reference temperature (To), 20◦C. T is your 6◦C and α is 0.0038(◦C)−1. So, using that you solve for ρ. If you keep up with the units though, you notice it comes out to be ohms*m and that isn't what you want.
So, the next equation you need is J=σE where E is your electric field (3026 V/m) and σ is the electrical conductivity which is the inverse of your answer you got in the previous equation. So find the inverse of that answer and multiply it by your electric field and that will give you the current density.
I hope this helps!
Explanation:
Answer: P = 40 W
Explanation: Power is defined as the amount of work per unit time or expressed in the formula of P = W /t
Work is the product of force and distance so W = Fd.
So the working equation will be:
P = Fd / t
= 20 N ( 2.0 m) / 1 s
= 40 W
Is the amount of power exerted.
Answer: They will NOT connect because like poles are facing each other, and like poles repel each other.
