1). A radio EM wave has a frequency somewhere between 10 KHz and 300 GHz, whereas a visible light EM wave has a frequency somewhere between 428,000 GHz and 790,000 GHz.
2). A radio EM wave has a wavelength somewhere between 1 mm and 30 km, whereas a visible light EM wave has a wavelength somewhere between 380-700 nanometers.
Answer: How does the temperature of the samples change?
As the temperature increases, the rate of reaction increases. Particles can only react when they collide. ... Increasing the temperature increases reaction rates because of the large increase in the number of high energy collisions. It is only these collisions that will produce the reaction. Low-temperature experiments prevent denaturation of samples. ... When the temperature of the protein water solution is reduced below the ... The FB peak position does not change but its intensity changes proportionally with variation of intensity of incident radiation.
Which way does the energy flow?
Energy flow in ecosystem occurs by food chain from producer to consumers. ... Then energy is transfered from producers to consumers, called as heterotrophs. Primary consumers are called as herbivores. Herbivores are eaten up by secondary consumers, called as carnivores. Energy flow is always unidirectional. Energy flows progressively from one trophic level to another and cannot revert back. In most of the natural ecosystems, energy comes from the sun, it is trapped by producers and then pass on to successive trophic levels in the form of food.
Explanation:
There are some mistakes in the question as units pressure and air density are not written correctly.The correct question is here
On a summer day in Narragansett, Rhode Island, the air temperature is 74°F and the barometric pressure is 14.5 lbf/in². Estimate the air density in kg/m³.
Answer:
p=1.175 kg/m³
Explanation:
Given data
Temperature =74 F
Barometric pressure=14.5 lbf/in²
To find
Air density
Solution
From ideal gas law
As mass/volume is pressure So
First we need to convert barometric pressure lbf/in² to N/m²
So
Now Substitute the given value and pressure to find air density
