Answer:
metal conducts heat faster than wood. which means the metal conducted heat away from your hand (or whatever it is) faster than wood.
Explanation:
just because they feel warm/cold doesn't always mean that it is warm/cold. if they both were sitting at room temp for a long time, then both will eventually reach the temp of the room. even though they are the same temp the metal will feel colder than the wood because of the thermal conductivity of the metal compared to the wood.
Interesting question. I'd take a guess that it could be either mirrors and light travelling in straight lines and being reflected, or optical fibres to achieve a perhaps similar result.
Answer:true
Explanation:
Displacement is the vector representation of a change in position. It is path independent and is equivalent to the straight line distance between the start and end locations. Distance is a scalar quantity that reflects the path traveled.
Answer:
4.6834625323 m/s
0 m/s
Explanation:
s = Displacement
t = Time
Velocity is given by

The bird's average velocity for the return flight is 4.6834625323 m/s
In the whole episode the bird went 5220 km away from its nest and came back. This means the displacement is zero.
Hence, the average velocity for the whole episode is 0 m/s
