A positive charge is placed in the center of an uncharged metal spherical shell with some thickness as shown above.
1. Draw the electric field that exists inside the empty volume enclosed by the shell.
(Empty except for
the positive charge.) Explain your drawing either in words or through use of a
diagram, or both.
2. Draw the electric field that exists inside the metal shell. Explain your drawing
either in words or
through use of a diagram, or both.
3. Draw the electric field that exists outside of the metal shell. Explain your drawing
either in words or
through use of a diagram, or both.
The drawing of the positive charge showing the electrical fields inside the empty volume enclosed by the shell is attached accordingly. See explanation below.
What is the explanation of the drawing the positive charge inside the center of the uncharged spherical metal?The electrostatic potential at any location outside the shell, assuming the center of the shell is Z, equals Z/4π∈₁r, where r is the distance from O.
It's also worth noting that the spherical shell's outer surface is an equipotential shell, which means that the electric field at any place inside the shell except O is zero.
Because the shell is metallic, charge Z will induce uniformly on the inner surface and +Z will induce uniformly on the outer surface, with O as the charge center.
As a result, an electric field will exist both within and outside the shell, but the total charge will remain the same.

A monochromatic beam of light is absorbed by a collection of ground-state hydrogen atoms in such a way that three different wavelengths are observed when the hydrogen relaxes back to the ground state.
Answer:
If the absorbed beam is monochromatic (one wavelength) then it excites the H atom to some state n.
When that state decays, some of the atoms may decay to state 1, others to state 2, and still others to state 3
The net energy emitted in such a case would depend on:
n -1, n - 2, n - 3 which would produce 3 different wavelengths

A body which is uniformly decelerated comes to rest in 5s after travelling of 10m. What is its initial velocity a distance
Answer:
4 m/s
Explanation:
v=u+ at and v^2=u^2+2as.
It is given that v=0,t=5 s and s=10 m.
⇒0=u+5a and 0=u^2+20a.
⇒a=−u/5 and a=−u^2/20.
⇒u/5 = u^2/20⇒u=4 m/s.
⇒ The initial velocity is 4 m/s.
Consider a man walking around a house in a rectangle pattern. He walks 70 feet across the front, 30 feet along the side, 70 feet along the back, and 30 feet along the other side o bring him back to where he began. How much distance did this man cover?
200 feet
100 feet
140 feet
70 feet
Answer:
200ft
Explanation:
To find out how much distance the man covered, you need to find the perimeter of the rectangle. To find the perimeter of a rectangle, the formula is:
P = (L + H) × 2
Step 1
Plug in the values for L and H.
P = (70 + 30) × 2
Step 2
Add 70 and 30, because you need to add parentheses first.
P = (100) × 2
Step 3
Remove parentheses, and multiply 100 by 2.
P = 100 × 2
P = 200
Thus, the man walked 200 feet in distance.
A motorcycle starts 20m west of a reference point. It moves at a constant velocity for 5s, reaching a position of 10m east of the reference point.
What is the motorcycle’s average velocity?
The motorcycle's average velocity will be 6 m/sec. The ratio of the overall distance traveled to the total time taken by the body is the average velocity.
What is average velocity?The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.
Total distance travelled by the motorcycle;
d=20 m+10 m

what evidence is there suggesting ellipticals may form from the mergers of 2 or more spiral galaxies
Elliptical galaxies could be formed by the collision and merging of two spiral galaxies.
What is galaxy?Galaxy is the huge collection of stars, interstellar gases, dust particles, stones. Galaxies tend to come in two shapes such as spirals and ellipticals.
In spiral galaxies, the stars orbit in a very thin disk, and all the stars move in the same direction. Two or more spiral arms wind around the center just like a pinwheel.
Selecting a sample of about 50 spiral galaxies that have collided and in the process of merging into a single object. We took infrared images using the UH 88-inch (2.2-meter) telescope, and obtained spectra of these mergers using one of the Keck telescopes.
Infrared images are used to see, if the starlight in these objects decreases with distance from the center of the galaxy the way it does in spirals or the way it does in ellipticals. The light intensity decreases exponentially in outward direction from the centers of spirals, but it declines much more slowly with distance from the center for ellipticals. It is found that at least 45 out of 51 mergers are ellipticals.
Thus, most of these mergers really are evolving into elliptical galaxies.

Mutations and New Traits. Before watching the video, list one or two questions you may have about mutations. Alternatively, you can list a few things you already know about mutations.
Answer:
No, there are multiple ways in which different mutations in the same gene can cause the same phenotype
Explanation:
Several different mechanisms of mutation can lead to the same phenotype. For example, lets say our phenotype is that flies have white eyes, and we know that this occurs in one particular gene that normally makes the eye colour red. (the red gene)
These mutations likely rendered the red gene ineffective (as the eyes are not red). However, this could happen in a variety of ways.
There could be a single base deletion in the first exon of the mRNA, changing the reading frame of the protein and messing up the entire sequence (a frame shift mutations)
The entire gene could be deleted
A single base could be substituted in an important site of the gene, for example, one which translates into a catalytic residue or binding site in the protein
There could be an inversion at the promoter region of the gene, such that a transcription factor can no longer bind to transcribe the gene.
There are countless other ways in which a mutation could have been caused. Therefore, just because we know the same gene is affected does not mean that we can assume the mutations are identical.
