Conduction stops when all substances have

Answer:-

It stops when the temperature of all the particles/atoms is equal.

Explanation:

When two objects or substances that have different temperature are placed in contact with each other then there will be flow of heat from hotter object to colder object.

This transfer of heat will continue until the temperature of both the objects become equal.

For example, if a metal box has temperature that is higher than another metal box adjacent to it which has temperature. Then heat will flow from to until the temperature of both the boxes become equal to .

Hence, we can conclude that conduction stops when all substances have same temperature.

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
