Answer:
When the entire lake reaches 40 F, the surface water cools further, dropping below 40 F. Because this water is now less dense than the surrounding water, it will stay on the top and continue to cool. Once the surface water falls to 32 F, it freezes. The freezing then spreads downward into the lake and the ice thickens

Why is aq. Na2CO, basic?
Answer:
Basicity is due to the increase in OH− ions. So, the more Na+ is hydrolysed more OH− are produced, hence aqueous solution of Na2CO3 is basic in nature.
14. Given that 16x⁴+ - 4x³– 4b²x² + 7bx + 18 is divisible by 2x + b,
(a) show that b³ - 7b² + 36 = 0,
(b) find the possible values of b.
Answer:
(a) check the explanation
(b) the possible values of b is 6i or -29
Explanation:
Given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
(a)
factor of the given function = 2x + b
then, 2x + b = 0
x = -b/2
substitute the value of b into the given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
[tex]16(\frac{-b}{2} )^4 -4(\frac{-b}{2})^3-4b^2(\frac{-b}{2})^2 +7b(\frac{-b}{2})+18=0\\\\b^4+\frac{b^3}{2} -b^4-\frac{7b^2}{2} +18=0\\\\\frac{b^3}{2} -\frac{7b^2}{2} +18=0\\\\multiply\ through \ by \ "2"\\\\b^3-7b^2+36 =0 \ (shown)[/tex]
(b)
b³ - 7b² + 36 = 0
b²(b - 7) + 36 = 0
b²(b - 7) = -36
b² = -36 or b - 7 = -36
b = √(-36) or b = -36 + 7
b = √(-1) x √(36) or b = -29
b = 6i or -29

Solve for the value of p.
|(3p+1)°
(p+7)
Answer:
P=43
Explanation:
As, the both angles are linear, so if we add them, we will get 180°.
So, p+7 + 3p+1 = 4p + 8
So, 4p + 8 = 180
So, 4p = 180 - 8
4p = 172
P= 172/4
P = 43
So p+7 + 3p+7 = 43 + 7 + ( 3x43 + 1) = 180
Therefore, p = 43

Answer:
Explanation:
The Clean Air Act of 1970 and the amendments since then have done a great job in requiring people to clean up the air over the United States. Emissions of the six major pollutants regulated by the Clean Air Act, carbon monoxide, lead, nitrous oxides, ozone, sulfur dioxide, and particulates, have decreased by more than 50%. Cars, power plants, and factories individually release less pollution than they did in the mid-20th century. But there are many more cars, power plants, and factories. Many pollutants are still being released and some substances have been found to be pollutants that were not known to be pollutants in the past. There is still much work to be done to continue to clean up the air.How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are:
Riding a bike or walking instead of driving.
Taking a bus or carpooling.
Buying a car that has greater fuel efficiency.
Turning off lights and appliances when they are not in use.
Using energy efficient light bulbs and appliances.
Buying fewer things that are manufactured using fossil fuels.
During most of the Mesozoic Era, the Earth was ________. A.warmer than present B.about as warm as present C.cooler than present D.experiencing wild temperature fluctuations E.Unclear from the data presented. If you choose this answer explain what you are seeing.
Answer:
A.warmer than present
Explanation:
During most of the Mesozoic Era, the Earth was warmer than present.
This is because during the Mesozoic era the land were far away from water bodies which led to prevalence of deserts while today the land are much more closer to the water bodies. It’s a known fact that water bodies help in the thermoregulation and cooling of the atmosphere.
This is the main and feasible reason why the Earth was warmer in the Mesozoic era than now.

What causes the wavelength of a particular beam of light change?
Answer:
Wave speed, frequency and wavelength in refraction
Explanation:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
Wave speed, wavelength in refraction and frequency causes the wavelength of a particular beam of light change.
What is wavelength of a light?The wavelength of light is the separation between both the two crests or troughs of the light wave. It is recognized by the Greek letter lambda (). Therefore, the term "wavelength" refers to the distance between the crest or trough of one wave and the wave that follows it.
The number of waves that travel through a single location in a specific amount of time determines frequency, and the distance between two subsequent troughs or crests determines wavelength. As a result of the inverse connection between wavelength and frequency, frequency falls as wavelength increases.
The wave slows down, but because its wavelength is shorter, its frequency doesn't change. Waves' frequency does not alter as they go from one medium to another. Waves slow down and shorten in wavelength when they move through denser media.

What is rock?
The rock, according to geology, is a part of the solid surface. The rock is the collection of these cemented mineral grains. The rocks are small and bigger. The small rocks are also known as pebbles. The type of natural resource is rock. The rocks are used for making the building.
The influence on the rock differs depending on whether it is acid rain or ordinary rain. Acid rain degrades rocks gradually as a result of chemical interactions between the acids and the ions in the stone. Pure water has a moderately acidic pH of 5.6, whereas acid rain has a pH around 4.2 and 4.4.
As a result, the normal rain from acid rain are the based on the rock breaks.
