Answer:
Explanation:
Wien's displacement law states that the radiation of the black body curve for different temperatures will give peak values at different wavelengths and this wavelength is related inversely to the temperature.
Formally the law of Wien displacement states that the black body's spectral radiation per unit of wavelength, will give peaks at the wavelength of 
which is given by the mathematical expression.
Here, b is proportionality constant with value of 
The wavelength of the peak of the Gaussian curve is inversely related to temperature in degree kelvin.
Answer:
Magnetism at atomic /sub - atomic levels is mostly due to charged particles called electrons. Electrons have spin which give them angular momentum and thus a magnetic moment associated with it. That is the cause of Magnetism at atomic levels. Electrons fill up orbitals in atoms in pairs.
Answer: Energy
Explanation: The ability to do work or cause change is called energy. Energy comes from many sources, and is found in two main forms. One form, potential energy, is energy that has the potential, in an object at rest, to do work later. An example of this would be a car parked at the top of a hill with its brakes on.
Answer:
for your computer, refridgerator, stove, car, lights, oven, microwave, electronic chargers, wi-fi router, and fans
