Water vapor forming droplets that form clouds directly involve which process

Let the ED50 of a recreational drug be defined as the amount required for 50% of a test group to feel high or get a buzz. If the

Anastaziya [24]

Explanation:

1) The ED50 value of ethanol = 470 mg per kg of person body = 470 mg/kg

Mass of person = 70 kg

Amount of ethanol required by person of 70 kg to get buzz:

$70 kg\times 470 mg/kg=32,900 mg$

A 70 kg party goer need to quickly consume in order to have a 50% chance of getting a buzz is 32,900 mg of ethanol.

Mass of ethanol in beer bottle = 13.9 g

Amount of ethanol required by person of 70 kg to get buzz:

$70 kg\times 470 mg/kg=32,900 mg =32.9 g$

1 mg = 0.001 mg

Bottles of beer would a 70 kg party goer need to consume:

$=\frac{32.9 g}{13.9 g}=2.367\approx 2$

Bottles of beer would a 70 kg party goer need to consume a 50% chance of getting a buzz is 2.

2)The LD50 value of ethanol = 4,700 mg per kg of person body = 4,700 mg/kg

Mass of person = 70 kg

Amount of ethanol required by person of 70 kg to have a 50% chance of dying:

$70 kg\times 4,700 mg/kg=329,000 mg$

A 70 kg party goer need to quickly consume in order to have a 50% chance of dying is 329,000 mg of ethanol.

Mass of ethanol in Jack Daniels bottle = 356 g

Amount of ethanol required by person of 70 kg to have a 50% chance of dying:

$70 kg\times 4,700 mg/kg=329.000 mg =329 g$

1 mg = 0.001 mg

Bottles of Jack Daniels would a 70 kg party goer need to consume to have a 50% chance of dying:

$=\frac{329 g}{356 g}=0.923\approx 1$

Bottles of Jack Daniels would a 70 kg party goer need to consume to have a 50% chance of dying is 1.

1.The use of land is determined both by physical factors such as topography, climate, soil types as well as human factors such as population density, technological capability and culture and traditions etc.
2. Common property resources (environmental) are natural resources owned and managed collectively by a community or society rather than by individuals.
3.

Wind erosion is a natural process that moves soil from one location to another by wind power. ... Wind erosion can be caused by a light wind that rolls soil particles along the surface through to a strong wind that lifts a large volume of soil particles into the air to create dust storms.
4. Terrace cultivation or terrace agriculture method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope. Though labour-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss.
