To cook food, a microwave oven converts electrical energy into electromagnetic energy. (A) Specifically, it pours high-power RADIO waves into the box.
Water molecules and fat molecules resonate (jiggle) with the radio waves, and the heat is generated IN THE FOOD.
I work with microwave radios.
-- To communicate high-speed data over a distance of 5 to 10 miles, we use a radio transmitter with a power output of 0.07 watt .
-- To communicate high-speed data over distances up to 80 miles, we use a radio transmitter with a power output of 1 to 2 watts.
-- To heat up a chunk of leftover meatloaf, a microwave oven pumps radio waves into the box with a power output of 1200 to 1500 watts ! !
The answer to this question would be 330 m/sec
Answer:
The study of the human perception of sound is called psychoacoustics.
Explanation:
Answer:
Explanation:
From the question we are told that:
Emissivity 
Absorptivity 
Rate of solar Radiation 
Generally the equation for Surface absorbed energy is mathematically given by
Generally the equation for Emitted Radiation is mathematically given by
Where
T=Temperature
Therefore
Specific heat capacity is the amount of energy required to raise the temperature of 1kg of a substance by 1 degree. Therefore, the higher the number, the more energy is required.
Hence, Steel will raise the most, since less energy is required to raise its temperature.
