Numbers on the left of zero are negative. Number lines go from smallest to greatest.
Answer: 117.8 nm
Explanation:
Given,
Nonreflective coating refractive index : n = 1.21
Index of refraction: = 1.52
Wave length of light = λ = 570 nm =
Hence, the minimum thickness of the coating that will accomplish= 117.8 nm
Answer:
321.39 m/s
Explanation:
m = Mass =
= Charge = -2.50 pC
= Charge = -3.10 pC
r = Radius = 3.75 μm
= Vacuum permittivity =
We have the relation
The Speed they need when very far away from each other to get close enough to just touch is 321.39 m/s
We have the relation
The acceleration is
Answer:
F = G M m / R^2 a = G M / R^2
aS / aE = (MS / RS^2) / (ME / RE^2)
aS / aE = 329390 * RE^2 / RS^2) = 1 If acceleration due gravity equal
RE^2 = 1 / 329290 * (6.96E8)^2
RE^2 = 1.471 E12
RE = 1.213E6 m
actual RE = 6.38E6 m (average density of sun < that of earth)
