Answer:
0.39
Explanation:
distance from the center (r) = 32 cm = 0.32 m
speed of the coin (v) = 110 cm/s = 1.1 m/s
acceleration due to gravity (g) = 980 m/s^{2} = 9.8 m/s^{2}
find the coefficient of static friction (k) between the coin and the turn table
frictional force = kmg
before the table begins to move, the frictional force balances the centripetal force (
)
therefore
frictional force = centripetal force
kmg =
kg = 
k = ÷ g
k = 
÷ 9.8 = 0.39
Eyepiece is magnifies the image so you can see it clearly. Compare and contrast how images form in a refracting telescope reflection telescope and microscope. ...Refracting telescope is uses two lenses to locate somethings. Reflecting telescope uses a large concave mirror to gather light.

The answer is Photosphere. The photosphere is the lowest layer<span> of the </span>solar<span> atmosphere. It is essentially the </span>solar<span> "surface" that </span>we see<span> when </span>we look<span> at the </span>Sun in "white" light. It is <span>like a glowing fog, so at a distance, it </span>looks<span> solid, the same way a cloud looks solid from a distance.</span>
