The answer is the Milky Way .
Answer:
Explanation:
For image formation in objective lens
object distance u = 14 +1 = 15 mm
focal length f = 14 mm .
image distance v = ?
lens formula
Putting the values
v = 210 mm .
B )
magnification = v / u
= 210 / 15
= 14
size of image = 14 x 1.1 mm
= 15.4 mm
= 15 mm approx
C )
For final image to be at infinity , image produced by objective lens must fall at the focal point of eye piece . so objective lens's distance from the image formed by objective must be equal to focal length of eye piece that is 21 mm .
21 mm is the answer .
D )
overall magnification =
D = 25 cm , f_e = focal length of eye piece
= 14 x 250 / 21
= 166.67
= 170 ( in two significant figures )

Answer:
The atomic number of phosphorus is 15.
Explanation:
It’s found after Si(Silicon) and before S(sulphur)
B. solid
Explanation:
The solid state of matter is made up of particles that build repeating patterns. Solid is one of the four physical states of matter.
- Matter is described as anything that has weight and occupies space.
- The four states of matter are solid, liquid, gas and plasma.
- Solid particles are known to be closely packed and held together by very strong attractive forces.
- Solid like sodium chloride are said to be crystalline because they have crystals.
- Crystals are ordered atomic structures formed by repeating units of the fundamental molecular units.
- The repeating patterns of the crystals builds to form a solid.
- Other states of matter do not posses the repeating crystalline structure of solids.
