Which characteristic is not a characteristic of plastic? a. easy to mold b. good conductor of heat c. lightweight and durable d. repels water

The answer is B. Good conductor of heat.

C. lightweight and durable

Explanation:

Since plastic material is an insulator so it is not a good conductor of electricity as there is no free electrons in it.

In general trends it is observed that bad conductor of electricity is also bad conductor of heat so it is insulated to heat also.

Also the plastic materials are not easy to mold because this material is not very easy to change shape and size.

Also plastic materials are not used as water repellent because it is not used as good water resistant materials.

So here correct answer would be

C. lightweight and durable

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
