The correct option is this: COLLISION BETWEEN THE METAL AND THE WOOD RAISE THE KINETIC ENERGY OF THE WOOD MOLECULES.The correct option is A.
The type of heat transfer that occur between solids is called conduction. Convection and radiation can not occur in solids and that is why the other options are wrong.
When two solids that have different amount of heat come in contact with each other, heat will be transfered to the one will less heat as a result of collision with the molecules of the hotter material.
Answer:

- 1 mm/min = 1.66667E-5 m/s
- 1 m/s = 60000 mm/min
<u>Now</u><u>,</u><u> </u><u>come</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>question</u><u> </u><u>-</u><u> </u>
Result : 2536 mm/min = 0.0422666667 m/s.
The models are used to represent what you are studying in this case would be a planet. A model of Saturn and its rings and the moons surrounding it would be fantastic to look at when you have no way of going there
Answer:
W = 30 N
Explanation:
Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.
<u>W = 30 N</u>
