invention of the microwave and with the popularity of fast food restaurants‚ food has become easier to prepare than ever. Do you think microwave ovens and fast food restaurants are beneficial to society? Use specific reasons and examples to support your answer. Most of the people prefer fast foods and foods cooked in microwave oven instead of preparing and cooking foods at home that takes longer. The trend of having food quickly has advantages and disadvantages. I think this kind of food is not beneficial

How a Microwave Works By Zach Betten [pic] What is a Microwave? A microwave oven or microwave is a kitchen appliance that cooks or heats food by using electromagnetic waves. This happens by using microwave radiation to heat materials such as water and other things within the food. This leads to food being more evenly heated throughout. Basic microwave ovens heat food quickly and efficiently. One setback is that they do not brown or bake food in the

Microwave power transmission (MPT) is one of the applications of microwaves to transmit power from one place to another place without the need for wires. It is the type of the Electromagnetic Radiations‚ one of the wireless energy transfer methods. Introduction: Firstly‚ we will talk about the term Microwaves‚ Microwaves can also be termed as Radio waves having wavelengths ranging from one millimeter to one meter and the frequencies from 300MHz to 300GHz. These are also known as millimeter waves

Radio waves and Microwaves Radio communications Radio waves are used to broadcast radio or television signals from transmitters‚ which are then converted into electrical signals with an aerial (which is made out of metal to absorb the radio waves) so you can hear and see them. When done so the aerial converts this wave into an electrical signal (because of the electromagnetic waves energy exciting particles in the aerial and causing them to oscillate/vibrate and thus create an electrical current)

which a known fraction of the power is measured so that the total may be calculated. A number of coupling units used for such purpose are known as directional coupler.

Attenuation will be maximum if the wane is placed at center. (a)

transmitting power without using wires i.e.‚ transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Microwave Power transmission(MPT). We also discussed the technological developments in Wireless Power Transmission (WPT). The advantages‚ disadvantages‚ biological impacts and applications of WPT are also presented. KEY WORDS Microwave Power transmission (MPT)‚ Nikola Tesla‚ Rectenna‚ Solar Power Satellites

when marginal revenue equals marginal cost. Because our costs are sunk we should lower our prices so that we can fill to capacity. 14.4 A manufacturer of microwaves has discovered that male shoppers have little value for microwaves and attribute almost no extra value to an auto-defrost feature. Female shoppers generally value microwaves more than men and attribute greater value to the auto-defrost feature. There is little additional cost to incorporating an auto-defrost feature. Since men and
