When cooking food in a microwave it is more important to rely on the internal temperature of the food because microwave do not adequately kills pathogens that may be in food. Microwave normally penetrate food to the depth of 1 to 1.5 only. In thicker foods, microwave doesn't usually reach the center of the food, the un-reached part normally cook by conduction.
Answer:
Thus, the induced current in the coil at is 9.98 A.
Explanation:
Faraday's law says
where is the number of turns and is the magnetic flux through the square coil:
Now,
;
therefore,
is the emf induced in the coil.
Now, the loop is connected to resistance; therefore, at
Thus, the current in the coil at is 9.98 A.
Answer:
When electricity is passed through an aqueous solution of sodium chloride, it gives hydrogen, chlorine and sodium hydroxide as a product. The balanced chemical equation is, This process is called as Electrolysis of Brin im in hardvard dont cheat and get good grades and become a graduate in hardvard
Explanation:
Answer:
The electromagnetic spectrum encompasses a continuous range of frequencies or wavelengths of electromagnetic radiation, ranging from long wavelength, low energy radio waves to short wavelength, high frequency, high-energy gamma rays. The electromagnetic spectrum is traditionally divided into regions of radio waves, microwaves, infrared radiation, visible light, ultraviolet rays, x rays, and gamma rays.
Explanation:Exploration of the electromagnetic spectrum quickly resulted practical advances. German physicist Henrich Rudolph Hertz regarded Maxwell's equations as a path to a "kingdom" or "great domain" of electromagnetic waves. Based on this insight, in 1888, Hertz demonstrated the existence of radio waves. A decade later, Wilhelm Röent gen's discovery of high-energy electromagnetic radiation in the form of x rays quickly found practical medical use.This was on my notes
