We are given with
M = mass of planet
R = radius of circular trajectory of the satellite
ms = mass of the station
mm = mass of the meteorite
ms = 10 mm
R/2 = new orbit distance
The speed of the meteorite can be solved using the law of conservation of momentum
ms vs + mm vm = (ms + mm) v
Since the new orbit distance is half the original
v = 2 vs
Substitute and solve for vs
Ionic compounds are always salts forming between a metal and a non-metal
Examples include, but are not limited to
NaCl
BaF2
Cs2O
Sometimes an ionic compound can be composed of a metal + a polyatomic ion
Examples of polyatomic ions include
Phosphate PO4 3-
Chlorate ClO3-
Some ionic compounds with these polyatomic ions include
CsClO3
Ba3(PO4)2
Hope this helps. I can’t do much good if I can’t see the options.
-A photon travels, on average, a particular distance, d, before being briefly absorbed and released by an atom, which scatters it in a new random direction.
-Given d and the speed of light, c, you can figure out the average time step and space step size (how often the photon “steps” and how far it “steps” each time).
-The size of the Sun is figured in terms of step size. Some surprisingly tricky math happens, involving “Brownian motion” and probabilities. Finally,
-The average time it would take to get to the surface of the Sun is found.
Answer:
Tangential Speed equals 5.57m/s
Explanation:
In the figure shown for equilibrium along y- axis we have

Resolving Forces along y axis we have

Similarly along x axis

............(ii)[/tex]
Dividing ii by i we have

In the figure below we have 
Thus solving for v we have

Applying values we get
v=5.576m/s
