Answer:
Electricity is which is possessed by the flow of electrons.
Magnitism is the process in which the magnet attract the things which consist magnetic substance.
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:
Potential difference though which the electron was accelerated is 
Explanation:
Given :
De Broglie wavelength , 
Plank's constant , 
Charge of electron , 
Mass of electron , m=9.11\times 10^{-31}\ kg.
We know , according to de broglie equation :

Now , we know potential energy applied on electron will be equal to its kinetic energy .
Therefore ,

Putting all values in above equation we get ,

Hence , this is the required solution.
