Parts made from blow molding are plastic, hollow, and thin-walled, such as bottles and containers that are available in a variety of shapes and sizes. Small products may include bottles for water, liquid soap, shampoo, motor oil, and milk, while larger containers include plastic drums, tubs, and storage tanks.
Answer:
None of the wavelength is in the visible range
Explanation:
Constructive interference of the reflected waves for different wavelengths can be estimated using:
λ = 2nd/m
where m is 1,2,3, ...
Therefore:
m=1, λ = 750 nm
m=2, λ = 750/2 = 375 nm
The limits of eye's sensitivity is between 430 nm and 690 nm. Beyond this range, the eye's sensitivity drops to approximately 1% of its maximum value.
Answer:
a) 1511 MW
b) 44%
Explanation:
The thermal power will be the electric power plus the heat taken away by the cooling water.
Qt = P + Qc
The heat taken away by the water will be:
Qc = G * Cp * (t1 - t0)
The Cp of water is 4180 J/(kg K)
The density of water is 1 kg/L
Then
G = 1.17 * 10^8 L/h * 1 kg/L * 1/3600 h/s = 32500 kg/s
Now we calculate Qc
Qc = 32500 * 4180 * (29.8 - 23.6) = 842*10^6 W = 842 MW
The total thermal power then is
Qt = 669 + 842 = 1511 MW
The efficiency is
η = P / Qt
η = 669 / 1511 = 44%
The earth rotates (spins) at the same time as it orbits in a circular motion around the sun. fun fact : it takes 365 days to complete 1 orbit for 3 years and then 366 days for a leap year! you don't have to put that last part but maybe for some extra points you can!
Answer: Producers have the greatest amount of available energy.
When an organism eats another organism, it gains energy.
Explanation:
A food chain is a linear sequence of transfer of food and energy when one organism is eaten by the other organism. A food web is the interconnection of two or more food chains. This happens when one organism belong to one food chain also consume organisms of same food chain or other food chain. A food chain includes trophic levels on the basis of the mode of feeding of the living beings.
Among the options given, Producers have the greatest amount of available energy. and
When an organism eats another organism, it gains energy. are correct.
Producers are the organism which are capable of producing their food either through photosynthesis or chemosynthesis. They are present at the base level of the food chain. They consist of large amount of energy as compared to all the trophic levels in the food chain.
When one organism eats other organism it gains energy because of the assimilation and digestion of the organism as food.
