How does the heat move through the space between the sun and the earth? match the heat transfer mechanisms in space and on earth with the correct description.

the choices are
1. electromagnetic waves transfer energy through space to earth
2. heat energy on earth escapes into space
3. moves from warmer to cooler
4. touching, direct contact
5. warm air circulates towards cooler polar regions
6. flow of heat energy through liquids and gases
7. heat energy transferred
8. responsible for weather patterns on earth
9. transfer of heat through soil by the movement of molecules
10. warm air in atmosphere rises and is replaced by cooler air

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate

An aircraft performs a maneuver called an "aileron roll." during this maneuver, the plane turns like a screw as it maintains a straight flight path, which sets the wings in circular motion. if it takes it 35 s to complete the circle and the wingspan of the plane is 11 m, what is the acceleration of the wing tip
