Answer:
pOH=11.3
Explanation:
pH= -log[H+]=-log[0.002]=2.7
pOH+pH = 14
pOH= 14-2.7=11.3
The orbital period is proportional to r^(3/2) and does not depend on the satellite's mass. Any object at Jupiter's position will have the same orbital period regardless of mass. The correct answer is 11.9 yr. <u>Option C.</u>
As the Earth rotates on its axis creating day and night, it travels around the Sun in an elliptical orbit taking about 365 1/4 days to complete. The Earth's rotation axis is tilted with respect to the orbital plane. This creates seasons. The elliptical nature of the Earth's orbit is due to the first forces pushing the Earth away from the Sun's disk.
The momentum of this throw being greater the Earth's orbit would have been more elliptical or it might have been completely ejected from the solar system forever. The Earth's orbit defines a two-dimensional plane called the Ecliptic. It takes about 365 days for the earth to revolve around the sun. After years of analysis, Kepler found that Mars' orbit was likely elliptical, with the Sun at one of his focal points of the ellipse. This led Kepler to discover that all planets orbit the Sun in elliptical orbits and that the Sun is at one of his two focal points.

Explanation:
There are quite a number of ways to increase the solubility of substances.
Solution is a homogeneous mixture formed by dissolving a solute in a solvent.
Here are some things that can increase the rate of dissolution;
- Grinding/pulverizing - helps to increase the surface area for the solvent to react.
- Stirring - to bring more solvent in contact with the solute intimately.
- Heating - to facilitate dissolution of solute in solvents.
