Convection is the process in which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated so it becomes less dense and rise above.
For example- In a pot of water on a stove the liquid t bottom is heated by conduction. The hot water has lower density and it rises above pushing the cold water downwards so it gets heated.

Explanation:
Given:
Let = mass of the asteroid and = orbital radius of the asteroid around the sun. The centripetal force is equal to the gravitational force
or
where
with T = period of orbit. Rearranging the variables, we get
Taking the square root,
Answer:
In any specified solar cycle, the highest number of sunspots is referred to as "solar maximum." The lowest number is referred as "solar minimum."
Explanation:
Around every 11 years, the sun passes through a solar cycle. The cycle is defined by increasing and decreasing sunspots— noticeable on a sun's surface as dark imperfections, or photosphere.
In any specified solar cycle, the highest number of sunspots is referred to as "solar maximum." The lowest number is referred as "solar minimum." The latest solar minimum was obtained in 2008
Answer:
If using radians: 16.2
If using degrees: 12.8
Don't forget your units
Explanation:
I assume that x represents the velocity?
If so, then just substitute the value t and solve
