What are greenhouse gasses? How does carbon dioxide enter the atmosphere? (Site 1)

Physics

Answer and explanation:

Greenhouse gases are carbon dioxide, water vapor, fluorinated gases, nitrous oxide, methane, and others. Carbon dioxide enters the atmosphere by respiration of plants, animals, and microbes. Plants also remove carbon dioxide during photosynthesis. The net result is that plants remove more carbon dioxide than they contribute. Microbes and fungi that decompose plants and animals also return the carbon to the atmosphere as carbon dioxide. These are all ways nature cycles carbon. Humans contribute carbon dioxide to the atmosphere when we burn wood, solid waste, and fossil fuels. When forests are burned to clear land, not only does the burning release carbon dioxide, but it eliminates trees that would otherwise be removing carbon dioxide by photosynthesis. Most of the human contribution is from burning fossil fuels in electrical power plants that burn coal or natural gas and in vehicles that run on petroleum products. Other industrial processes also contribute carbon dioxide to the atmosphere, but to a lesser extent.

Answer:

greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range

Explanation:

Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

D. 51 N. The minimum applied force that will cause the television slide is 51 N.

In order to solve this problem we have to use the force of static friction equation Fs = μs*n, where μs is the coefficient of static friction, and n is the normal force m*g.

With μs = 0.35, and n = 15kg*9.8m/s² = 147 N

Fs = (0.35)(147 N)

Fs = 51.45 N

Fs ≅ 51 N

It took a crew 9 h 36 min to row 8 km upstream and back again. If the rate of flow of the stream was 2 km/h, what was the rowing
babunello [35]

Answer:

3 km/h

Explanation:

Let's call the rowing speed in still water x, in km/h.

Rowing speed in upstream is: x - 2 km/h

Rowing speed in downstream is: x + 2 km/h

It took a crew 9 h 36 min ( = 9 3/5 = 48/5) to row 8 km upstream and back again. Therefore:

8/(x - 2) + 8/(x + 2) = 48/5      (notice that: time = distance/speed)

Multiplying by x² - 2², which is equivalent to (x-2)*(x+2)

8*(x+2) + 8*(x-2) =  (48/5)*(x² - 4)

Dividing  by 8

(x+2) + (x-2) = (6/5)*(x² - 4)

2*x = (6/5)*x² - 24/5

0 =  (6/5)*x² - 2*x - 24/5

Using quadratic formula

x = \frac{2 \pm \sqrt{(-2)^2 - 4(6/5)(-24/5)}}{2(6/5)}

x = \frac{2 \pm 5.2}{2.4}

x_1 = \frac{2 + 5.2}{2.4}

x_1 = 3

x_2 = \frac{2 - 5.2}{2.4}

x_2 = -1\; 1/3

A negative result has no sense, therefore the rowing speed in still water was 3 km/h
