The shorter the wavelength, the more frequency.
Answer: b
Explanation:
I could be wrong but because it’s at zero it can be calculated
Answer:
Alaska: Hydrokinetic Energy Campbell CR9000X used for in-stream hydrokinetic device evaluation. Marine hydrokinetic energy power generation is an emerging sector in the renewable energy portfolio. Hydrokinetic devices convert the energy of waves, tidal currents, ocean currents or river currents into electrical power.
Answer:
11 kg of gas are emmited to the atmosphere
Explanation:
The problem consists in calculating the total mass of the gases produced in the combustion reaction of the carcoal.
In this case we consider the simple combustion reaction:
C+O2 -> CO2
In relation 1:1 molar with the oxygen.
In this case, the limitant reactant is the carbon, so we make the calculations based in the 3kg of carbon combusted.
First we convert the mass of carbon into mol of carbon
m,C=3kg=3000 g of C
Then we have the mol
n,C=3000g/(12 g/mol)=249.77 mol C
This number also corresponds to the number of oxygen mol reacting with the charcoal. Therefore we calculate the mass of oxygen.
m,O2=249.77 mol *(32 g/mol) = 7990 g =7.99 kg, aproximately 8 kg
Then the total mass of gas is the mass of charcoal plus the mass of oxygen
m,total=3kg + 8kg=11kg
Answer:
Answer choice D!
Explanation:
When it comes to running during a hot day, the human body responds to extensive periods of heat by producing sweat. Sweat is necessary in order of cooling down the body, so that is why I figured it would be that answer. I hope this helped!
