<h2>Answer: i agree B</h2><h2>Explanation:</h2>

A the gun wasn't found. this would be an issue but still possible to determine distance with gunpoweder residue

C a hollow point round was used. that is just some type of bullet. i dont remember any specific lesson on bullet identification

D the gun was decades old. this could also be an issue, but it doenst have anything to do with distance

So it must be B. unless the victim could tell you how far the shooter was. but then we would have to consider consciousness, if the victim was facing the shooter, and if the victim was sober. but that's juts overthinking things. it 's most likely B

I would think 2. The victim survived the incident because the victim would have moved or gotten up, which changes the distance between the victim and the gun.

Explain the ways that carbon dioxide is added to the atmosphere. How is it removed? Does most carbon enter the atmosphere as car

Licemer1 [7]

Answer:

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent.Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating

Rank the compounds in each set in order of increasing acid strength.

Viktor [21]

Answer:

See explanation

Explanation:

For this question, we have to remember the effect of an atom with high electronegativity as "Br". If the "Br" atom is closer to the carboxylic acid group (COOH) we will have an inductive effect. Due to the electronegativity of Br, the electrons of the C-H bond would be to the Br, then this bond would be weaker and the compound will be more acid (because is easier to produce the hydronium ion $H^+$ ).

With this in mind, for A in the last compound, we have 2 Br atoms near to the acid carboxylic group, so, we will have a high inductive effect, then the C-H would be weaker and we will have more acidity. Then we will have the compound with only 1 Br atom and finally, the last compound would be the one without Br atoms.

In B, the difference between the molecules is the position of the "Br" atom in the molecule. If the Br atom is closer to the acid group we will have a higher inductive effect and more acidity.

See figure 1

I hope it helps!

When an object is lifted 10 feet off the ground, it gains a certain amount of potential energy. If the same object is lifted 30

Elden [556K]

Answer: 3 times as much the potential energy

Explanation:

Potential energy is the energy possessed by an object by virtue of its position.

$P.E=m\times g\times h$

m= mass of object

g = acceleration due to gravity

h = height of an object

When same object with same is lifted from 10 feet to 30 feet. The height has increased 3 times , thus the potential energy will also get 3 times as much.
