The work done by the stick on the hockey puck is equal to the magnitude of the force times the distance covered by the puck:
And the power of the stick is equal to the ratio between the work done and the time taken, therefore
Answer:
The chemical energy of the battery was reduced in 10800J
Explanation:
The first thing to take into account is that the stored energy in a battery is in Watts per second or Joules (
). It means that the battery provides a power for a certain time.
The idea is to know how much 
has been consumed by the circuit.
The first step is to know the power that is consumed by the circuit. It is 
. The problem says that the circuit consumes a current of 5.0A with a voltage of 6.0V. It means that the power consumed is:
The previous value (30W) is the power that the circuit consumes.
Now, you must find the total amount of power that is consumed by the circuit in 6.0 minutes. You just have to multiply the power that the circuit consumed by the time it worked, it means, 6.0 minutes.
You must convert the minutes unit to seconds. Remember that 1 minute has 60 seconds.
Thus, the chemical energy of the battery was reduced in 10800J

Answer:
Option B
Tile is a good conductor : a carpet is a good insulator
Explanation:
When the feet comes in contact with the tile, the tile conducts heat from the body making one to feel cold. However, since carpet is made of insulators such as cotton, they don't conduct heat, therefore, it slows down the flow of the heat which would make it feel warm so our feet do not feel much more colder as it does with the tiles.
