C. copper
Explanation:
Copper is the best conductor of heat from the given options. Plastic, wood and cotton are all poor conductors other wise known as insulators.
Metals are typically good conductors of heat.
- they generally do not have a high specific heat capacity which implies that they get heated easily.
- a good conductor allows heat to flow fast and it simultaneously loses heat readily too.
- copper is a good conductor, when heat its perfectly allows heat to pass through
- when heat is removed, it loses it very fast.

Answer:
During the section CD , the speed is fastest.
Explanation:
The rate of change of distance is called speed.
Speed = distance / time
Its SI unit ism/s. It is a scalar quantity.
The slope of the distance time graph is given by the speed of the object.
Here, the speed of AB is 30/3= 10 m/s .
The speed of BC is = 0 m/s
The speed of CD is (50 - 30)/(6 - 5) = 20 m/s
So, the speed is maximum during the section CD.

Answer:
35000 KJ
Explanation:
The equation for the kinetic energy is given by the formula :
OR 
Units will be kilojoules since the units of mass was kilograms .
Our final answer is 35000 KJ
Hope this helped and have a good day
Answer:
Explanation:
Formula for AVERAGE acceleration
is Final Velocity
is Initial Velocity
is Final Time
is Initial Time
Most of the time, the initial time will be 0, so you won't have to subtract.
