D
Answer:
D. Waste management issues
Explanation:
Answer A: The five major types of pollution - water pollution, air pollution, land pollution, light pollution, noise pollution - have negative effects on the environment, on human health, and our planet as a whole.
Answer B: Urban Heat Island (UHI) is an urban area that is significantly warmer than its surrounding rural areas due to human activities. UHI decreases air quality.
Answer C: The increased use of surrounding land is the main cause of biodiversity loss.
Answer D: Any field of environmental management help people to solve pollution problems. So, D is the correct answer.

This problem can be solved using the Combined Gas Law. The formula for it is
Let's go ahead and plug in the known values. Since pressure remains the same, it does not matter what value we plug in, so let's assume 1 atm for both sides.
Now, we just need to solve for the unknown. Start by simplifying the left side and right numerator.
0.001 =
Multiply both sides by x.
0.001x = 0.140
Divide both sides by 0.001.
x = 140 K
Convert that to Celsius (K = C + 273)
140 = C + 273
C = -133
So, the volume of your gas will be 0.140 L at -133° C.

Explanation:
One food Calorie is equal to 1 kilocalorie, that is, 1000 calories. A SI unit of energy is the joule (symbol J), where 1 cal = 4.184 J. The heat produced by chemical reactions is often expressed in kilocalories, as well as in kilojoules (kJ), where 1 kcal = 4.184 kJ.
First, we convert the energy of the photon to Joules. Then, we use the equation for energy of a photon, E=hc/λ, rearranged to solve for λ (wavelength). Substituting the known values into this equation, we can calculate the wavelength of the photon.
The energy of a photon is given in calories, but in physics, it's usually measured in Joules, so we first need to convert our energy to the appropriate unit. Thus, the energy of the photon is 4184 Joules (1,000 calories x 4.184 Joules/calorie).
The energy of a photon is also related to its wavelength through the equation E=hc/λ, where h is Planck's constant (6.63 x 10^-34 J.s) and c is the speed of light (3.00 x 10^8 m/s). By rearranging the equation, we find λ=hc/E. Substituting the given numbers for Planck's constant, the speed of light, and the energy of the photon, we find that λ = (6.63 x 10^-34 J.s)(3.00 x 10^8 m/s) / 4184 J.
Calculating these values, we will arrive at the wavelength of the radiation emitted by this photon.
