The statement that best describes convection would be:
"After the stove is turned off, convection currents continue to transfer energy through the water for a period of time."
By definition, convection is <span>the movement caused within a fluid by the tendency of hotter and less dense material to rise, and colder, denser material to sink, which results in the transfer of heat.

Answer:
17.56 N
Explanation:
Given that,
Mass of a crate, m = 5 kg
It is on a 21.0° hill
We need to find the y component of the weight.
y component = mgsinθ
Put all the values,
y-component = 5×9.8×sin(21)
= 49×sin(21)
= 17.56 N
So, the y-component of the weight is 17.56 N.
Gas is a state of matter that has no fixed shape and no fixed volume. Gas particles spread out and are evenly spaced throughout a container. ... Gas particles spread out to fill a container evenly, unlike solids and liquids
The bag moves to the left.
This is because of Newton's third law of motion that states:
For every action force on a body, there is an opposite and equal reaction force.
Thus pushing the bag from the right makes it move to the left.
