16. Solids cannot transport heat through convection. Because solids are stuck in place so they can't flow and since they can't flow, there is no convection.
17. It is because the metal conducts heat faster that it feels colder than the wood, which conducted heat slower. In other words metals are good conductors of heat. It takes away your body heat as you touch it and which makes your body temperature to drop, therefore you feel the coldness when you touch a piece of metal.
Displacement measures how far it is from the starting point and the final location, which in this case is the distance between Honolulu and Los Angeles. The difference between distance and displacement is that distance measures how far the object actually travels. For example, the airplane may not fly in a straight line and it may have detours, making the distance much greater than the displacement.
On the other hand, the plane could fly at different speeds at different periods of time. It will be so much more complicated if we have to calculate it. That's why this question only asks you to calculate the average velocity of the plane, ie. 
So, we have
the required average velocity = 
= 511.6 miles/hour
Hope this helps!
Answer:
A. Moving the mass from Point C to B, although it involves a greater distance, requires less force to do the same amount of work.
Explanation:
The amount of work will be the same either way. By going from C to B, the mover will exert less force over a greater distance, which is easier than exerting a greater force over a shorter distance.
A solution is a homogeneous mixture of two or mores substances at molecular level mainly solute and solvents. A solution may be saturated, supersaturated or unsaturated. A saturated solution is when the solution has dissolved the maximum solute at a given temperature, unsaturated solution is a solution which can still dissolve more solute at a given temperature to achieve saturation. In this case, if a solution is forced to dissolve more solute than it normally can dissolve, the solution is supersaturated.
