What evidence do the positions of the peaks and dips in its spectrum provide about an object?.
The positions of the peaks and dips in its spectrum provide evidence about the ELEMENTAL COMPOSITION of an object. Each element can absorb light at determined wavelengths.
Each element can absorb light rays at determined wavelengths because elements are composed of different atoms.
Spectroscopy is a field of study focused on the interaction between the atoms of an element and electromagnetic radiation as a function of the wavelength.
This field (spectroscopy ) studies the absorption and emission spectra of light by matter, which can be used to determine the elemental composition of an object.

Bob plants some seeds in a small cup. He puts the cup in the light and waters the soil every day. After 4 days, the seedlings emerge from the soil. What can bob conclude?.
What Bob can conclude after 4 days when the seedlings emerged from the soil is that;
The seedlings exerted an upward pushing force on the soil.
Since he planted some seeds in a cup of soil and puts water and light daily into it, it means that the seedling is supposed to germinate and begin to grow.
However, we are told that after 4 days, the seedlings emerged from the soil. What this means is that the seedlings didn't germinate and as such they instead forced their way up the soil with an upward pushing force.

During photosynthesis, plants capture sunlight energy to make glucose. Then they are able to store that glucose energy. What macromolecule is being referred to?.
Answer:
starch
Explanation:
Photosynthetic autotrophs capture light energy from the sun and absorb carbon dioxide and water from their environment. Using the light energy, they combine the reactants to produce glucose and oxygen, which is a waste product. They store the glucose, usually as starch, and they release the oxygen into the atmosphere.
At the time of the photosynthesis, the plant captures sunlight and makes glucose which is stored as a form of energy. The molecule here refers to starch.
What is starch?The starch is soft, white, tasteless, and is insoluble in cold waters such as alcohol or other solvents.
The autotrophs or the plants that make their own food process sunlight that itself a fork of energy and thereby absorbed carbon and water from the environment. The combined reacts to make glucose and oxygen. Thus stored glucose is a starch.

How did using metal help ancient chinese people increase food production.
Which of the following processes suggest that matter is made up of minute particles.
Answer:
the answer is evaporation
Explanation: Evaporation is the process by which a liquid transforms into vapor (a gas). When some material is in its liquid phase, its particles are really close together (but not as much as we would see in a metal). As the temperature of the liquid increases, also does the kinetic energy of the particles. This cause the particles in the water to move a lot faster, thus its oscillations are larger. This causes an increase in the volume of the material.

F(x, y) = e−x + y2, e−y + x2 , c consists of the arc of the curve y = cos(x) from − ???? 2 , 0 to ???? 2 , 0 and the line segment from ???? 2 , 0 to − ???? 2 , 0.
Given that y = cos(x) makes up part of the boundary of C, I suspect you mean the given points to be (-π/2, 0) and (π/2, 0).
I also assume the given vector field is
[tex]\vec F(x,y) = \left\langle e^{-x} + y^2, e^{-y} + x^2 \right\rangle[/tex]
Since [tex]\vec F[/tex] has no singularities on C or in its interior, Green's theorem applies:
[tex]\displaystyle \int_C \vec F(x,y) \cdot d\vec r = \iiint_D \frac{\partial(e^{-y}+x^2)}{\partial x} - \frac{\partial(e^{-x}+y^2)}{\partial y} \, dA = 2 \iiint_D (x + y) \, dA[/tex]
where D is the interior of C, the region
[tex]D = \left\{ (x, y) : -\dfrac\pi2 \le x \le \dfrac\pi2 \text{ and } 0 \le y \le \cos(x) \right\}[/tex]
The integral then reduces to
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \int_0^{\cos(x)} (x + y) \, dy \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac12 \cos^2(x) \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac{1 + \cos(2x)}4 \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 4x\cos(x) + 1 + \cos(2x) \right) \, dx[/tex]
Since 4x cos(x) is an odd function over the symmetric interval [-π/2, π/2], its contribution to the integral is 0, and the remaining integral is trivial.
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 1 + \cos(2x) \right) \, dx = \boxed{\frac\pi2} [/tex]
A group of campers walked at a speed of 4. 5 mph from their campsite to a rest area. Their return trip to the campsite took 15 minutes longer because their speed was only 4 mph. What is the distance between the campsite and the rest area?.
The distance between the campsite and the rest area is 9 miles.
The given parameters:
Initial speed of the campers, u = 4.5 mphFinal speed of the campers, v = 4 mphLet the time of motion from the campsite to rest area = t (hours)
Time for return trip = t hours + 15 mins
= (t + 0.25) hours
Let the distance between the campsite and rest area = d
d = 4.5t
d = 4(t + 0.25)
4.5t = 4(t + 0.25)
4.5t = 4t + 1
4.5t - 4t = 1
0.5t = 1
t = 2 hours
The distance between the campsite and the rest area is calculated as follows;
d = 4.5t
d = 4.5 x 2
d = 9 miles
Thus, the distance between the campsite and the rest area is 9 miles.

To write an essay that analyzes the relationship between the entirety of "Young goodman brown" and a passage that relates to the development of the theme author, characters or plot, we can choose the following excerpt:
"And when Brown looks up to meet his wife Faith, it's a metaphor for how our faith cannot save us from committing sins, because those who built those beliefs were sinners, and so most religions are based on lies."This passage relates to the tale's central premises, that humanity lives in a state of depravity, in keeping with the Calvinist belief that God has destined salvation to some through his grace.
Therefore, based on Brown's self-examination, the tale demonstrates how sin is a reality for all humans, regardless of their good practices and actions.
