Answer: Starting of with Chemical Engineering something that they may encounter is a lack of adeptness man puissance. People that are working there are not much adept or having cognizance regarding to chemical industry. Something someone with a Civil engineering might encounter is the quandary of sustainable construction, and amendment construction site safety. To go on , something that Electrical engineering might encounter is a Non technical , Virtually an electrical engineer has to deal with an astronomical range of machines , control panels,instruments. For example you are working with circuit breakers,as anon as you’ll have expertise on any particular type of circuit breaker, there's a transmutation in trend and the CB you are working with is already obsolete. And last but no least , Something someone might encounter while doing Mechanical engineering is there toxic substances because their work environment is susceptible to fires, explosions, structural failures and equipment malfunctions.
Answer:
<em>The goal of UAT is to make sure the software, website or application can handle all required tasks in real-world scenarios, according to user specifications. This type of UAT process is often called beta testing.</em>

Answer:
Q= - 7 KJ
Heat is rejected
Explanation:
In first process:
Process is adiabatic so heat transfer will be zero.
Q= 0 For adiabatic process
Now from first law of thermodynamics
Q = ΔU + W
ΔU is the change in internal energy
Q is the heat transfer
W is the work.
So here Q= 0
And work is transfer to the system .It means that work done on the system so it will be taken as negative.
W= - 12 KJ
Q = ΔU + W
0 = ΔU -12
ΔU = 12 KJ
It means that in first process internal energy of system increase.
In second process:
non-adiabatic process and work done by system is 5 KJ.
Q = ΔU + W
U is the point function and it does not depends on the path follows it depends only on final and initial states.
So fro second process
ΔU = - 12 KJ
Q= -12 + 5
Q= - 7 KJ
In magnitude Q= 7 KJ
It mean that heat is rejected from the system because it give negative sign.
Answer:
t=13.49 min
Explanation:
Given that
I=300 A
A= 0.21 cm²
L= 0.85 m
Number of charge carriers per unit volume = 8.49 x 10²⁸ m⁻³.
We know speed of the electron given as
V=J/ne
J= I/A
So
V=I/neA
V=0.00105 m/s
lets take t is the time when electron travels from car battery to the starting motor
t = L/V
t=809.52 s
t=13.49 min
Answer:
See explaination
Explanation:
Rolling resistance which in some occassions can be called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface.
In order to calculate our rolling resistance, there should be a force.
