Question:
Which situation describes the best example of rotational motion?
A. Craig sent the pool ball spinning toward the side pocket.
B. The skater repeated the figure eight on the ice.
C. Sara spun the dreidel on its pointed end.
D. The mouse ran in circles around the mousetrap.
Answer :
C
Explanation:
It's C, because it is spinning. It can't be D because it's going in a circle, not spinning. it can't be A because it doesn't really make sense. It can't be B because the Skater is repeating, not rotating. So the only logical answer is C.

How thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.
<h3>Density of the Neutron star</h3>
Density
ρ = m / V
Where:
ρ= density
m = mass of the planet 5.98 10²⁴ km
V =volume of the spherical layer
Volume of a sphere
Volume = 4/3 π r³
Mass = 1.5 = 1.5 1,991 10³⁰
Mass= 2.99 10³⁰ kg
Density:
ρ = 2.99 10³⁰ / [4/3 π (10 10³)³]
ρ is = 7.13 10 17 kg / m³
V = 5.98 10²⁴ / 7.13 10¹⁷
V = 8,387 10⁶ m³
Thickness of the layer
V = 4π r² e
e = V / 4π r
e = 8,387 10⁶ / [4π (10 10³)²]
e = 6.67 10⁻³ m
Inconclusion how thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

Answer:
3. Homogenous and unsaturated
Explanation:
Since your given information mentions 50 grams of solvent and 5 grams of solute, you must double each amount because "
Table G Solubility Curves" in the Regents Chemistry Reference Table notates curves based off of 100 g samples of water. Therefore, you must look for how soluble 10 grams of KCl is in 100 grams of water at 25 degrees Celsius.
As the picture shows, 10 grams of KCl is well below the curve for saturation, meaning that the solution is undersaturated.
As for the second part of the answer, we can tell that the solution is homogenous (of uniform composition) because there is no possibility of the salt, KCl, falling out of solution and making the mixture heterogenous (of mixed composition).
Putting all of those ideas together, we can tell that the answer to this question is:
