Light Spectrum:
Gamma Rays; X- Rays; Ultraviolet Rays; Infrared; Micro; Radio
I'm guessing green means the color wave
So it should be: Radio-Infrared- Green - UV - Gamma
This is because frequency decreases when going from left to right on the Light Spectrum!
Answer:
efficiency of heating with this oven is 51 %
Explanation:
to raise the temp of 200 ml of coffee from 30°C to 60°C the energy input to microwave oven is:
1100 J/s x 45 = 49,500 J
AT 100% efficiency
For 1°C the energy required to raise the temperature of 1 ml = 4.2 J
So for 30 C°, 1°C the energy required to raise the temperature of 200 ml =
Q = (4.2) (200)(30) = 25,200 J
efficiency = 25,200/49,500 = 0.51 = 51%
mass * temp change * specific heat
make sure the specific heat value is in Joules
Answer:
Sample Response: Seeds travel in several different ways. They can travel in the wind, like a dandelion does, or in water, like a coconut does. Seeds also travel with the help of animals. For example, squirrels collect and hide nuts, while birds carry seeds on their beaks or feet. Birds also eat seeds and drop them in a new location. Some seeds get stuck on animal fur or on people’s clothing.
