<span>Youll need to use Wiens Displacement Law:\[T=\frac{ 2.8978*10^{-3}m∙K }{ \lambda _{\max} }\]Note that the units of the constant are meter∙Kelvin, so youll need to convert 350nm to meters.</span>
The efficiency<span> of a heat engine can be calculated as the ratio of the work obtained to the heat energy put in at the high temperature,
efficiency = Work_max/T</span>high<span>.
or
efficiency=TH-TL/TH,
where TH is the high temperature and TL is the low temperature.</span><span>
In our case the heat engine operates between 600K and 800K. SO, TH=800K and TL=600K.
The efficiency is: e=800-600/800=200/800=0,25</span>
A magnet is made from materials that is magnetized and create its own persistent magnetic field while a electromagnet is mad from coil of wire which acts as a magnet when electric current passes through it.
Answer:
The answer is "Option A".
Explanation:
In the given scenario, Two metal plates were produced in contrast to values separated by a small distance and three potential points for just a slight net charge are accessible. All three points would have the same electrical energy since the power generation is consistent from both sides as well as the position is placed at a slight net value so it has the highest electrical energy.
