Answer: The soil will be warmer than the water.
Explanation:
The heat (thermal energy) absorbed can be found using the following equation:
Where:
is the heat
is the mass of the element
is the specific heat capacity of the material.
is the variation in temperature
<u>In the case of soil we have:</u>
(1)
Where:
<u>In the case of water we have:</u>
(2)
Where:
Isolating from both equations:
(3)
(4)
(5)
(6)
Comparing (4) and (6) we can find the soil will be warmer than the water.
<span>In order to calculate an average, we should sum all numbers and divide them by quantity.
Let’s work with qualifications first. Let’s say you got a 10 in 1 exam, then an 8 in 2 exams and a 4 in 2 exams. Your average will be:
= (10*1+8*2+4*2) / 5 = 6.8
If 6 is the minimum, you will pass.
There is another way to calculate this average: applying distributive property.
= 10*1/5+8*2/5+4*2/5 = 6.8
Remember you can convert the fractions into equivalent fractions: 1/5 = 20/100; 2/5 = 40/100
= 10*20/100+8*20/100+4*20/100 = 6.8
We actually don’t have the number of atoms of each mass… we have the percentage instead! So we need to learn this last method for atoms.
Let’s go back to our atoms problem:
73.71 % of atoms have a mass of 27.98 u
14.93 % of atoms have a mass of 28.98 u
11.36 % of atoms have a mass of 29.97 u
So let’s put that in the formula:
Average mass = 27.98 u*73.71 /100 + 28.98 u*14.93 /100 + 29.97u*11.36 /100
So what you have to know is that a percentage can be converted into a fraction, and you should work that fraction in order to find the average. We can make the calculus shorter putting 100 as the common denominator:
Average mass = (27.98 u*73.71 + 28.98 u*14.93 + 29.97u*11.36)/100
So actually we are taking the percentage as if it was the quantity, and 100 as if it was the total (the total of all percentages is always 100). Maybe we don’t have 100 atoms, but it will be the same proportion anyway, whatever number we have! And here it is the result:
Average mass = 28,36u

Polarization of light is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.
<h3>What is polarization of light?</h3>
The question is unclear but I will try to explain what is meant by polarization of light. We know that light is an electromagetic wave and vibrates in all directions.
The polarization of light enables light to vibrate in a specified direction. This is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.
