Answer:
2,25 g/cm3
Explanation:
Hi, you have to know one thing for this.. Density = mass/Volume,
When you have the loaf of bread with 3100 cm3 and a density of 0.90 g/cm3, the mass of that bread is 2790 g because of if you isolate the variable mass from the equation you get.. mass= density x volume
Later, have on account the mass never changes, so you crush the bread and the mass is the same.. so when you have the mashed bread.. you know that the mass is 2790 g and the volume of the bag is 1240 cm3, so you apply the main equation.... density=2790 g / 1240 cm3 , so density = 2,25 g/cm3
An good example would be using a Bunsen burner to heat water in a tin container. The flame initially heats the tin can by radiating heat. Conduction then transfers heat from the tin can to the water. The convection process causes the hot water to then climb to the top.
<h3>What is Bunsen Burner?</h3>
A laboratory piece of equipment known as a Bunsen burner, which bears Robert Bunsen's name, produces a single open gas flame and is used for heating, sterilization, and combustion. Natural gas, liquefied petroleum gas, such as propane, butane, or a combination, are all acceptable choices for the gas.
<h3>What three types of flames can you get from a Bunsen burner?</h3><h3>Bunsen burner flames come in three primary categories:</h3>
- Because it is simple to notice in a well-lit space, a yellow flame is also referred to as a safety flame.
- Flaming Blue. A burner's specific flame can reach temperatures of 500 degrees.
- Blue Flame in Flames The roaring blue flame setting on a Bunsen burner produces the hottest flames.

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
Answer:
Or in the other way:
Explanation:
For this case we need to remember that hectare is a measure of area. And we have the following ratios:
We can convert this into
We can convert this into
By dimensional analysis we assume that we can find the ratio in terms of distance like this:
And if we find the ratios in terms of distance we got:
Or in the other way:
Yellow has the lowest density. I took the test and got this question correct. :)
