Explanation:
Answer:
Exact answer: a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
Answer:
Equilibrium Temperature is 382.71 K
Total entropy is 0.228 kJ/K
Solution:
As per the question:
Mass of the Aluminium block, M = 28 kg
Initial temperature of aluminium, 
= 273 + 140 = 413 K
Mass of Iron block, m = 36 kg
Temperature for iron block, 
= 273 + 60 = 333 K
At 400 k
Specific heat of Aluminium, 
At room temperature
Specific heat of iron, 
Now,
To calculate the final equilibrium temperature:
Amount of heat loss by Aluminium = Amount of heat gain by Iron
Thus
= 273 + 109.71 = 382.71 K
where
= Equilibrium temperature
Now,
To calculate the changer in entropy:
Now,
For Aluminium:
For Iron:
Thus
Answer:
Explanation:
Let assume that heating process occurs at constant pressure, the phenomenon is modelled by the use of the First Law of Thermodynamics:
The specific enthalpies are:
Liquid-Vapor Mixture:
Saturated Vapor:
The thermal energy per unit mass required to heat the steam is:
Answer:
D. Brake
Explanation:
NJMVC is an acronym for New Jersey Motor Vehicle Commission and it is an agency of government that was established in 2003. NJMVC is saddled with the responsibility of inspecting, titling of number plates and registration of motor vehicles, as well as licensing of drivers in New Jersey, United States of America.
The NJMVC subject the applicants (drivers) to a series of test before they are issued a valid driver's license, some of these tests include;
1. Vision test.
2. Knowledge test.
3. Road test.
All of the above mentioned tests must be passed by a driver before he or she are issued a valid driver's license.
Some of the test drive requirements are;
- Valid registration documents.
- Valid sticker of inspection.
- No obstacle or center consoles should prevent the examiner from accessing both the foot brake and parking brake.
Hence, NJMVC will reject a vehicle from the road test if the examiner does not have access to a brake. Thus, the brakes are required to be in good working condition prior to the road test.
However, if an applicant (driver) passes the road test he or she would be issued an authorization for licensing by the examiner and then a digital driver's license by the motor vehicle commission.
