Answer:
Part a)

Part b)

Explanation:
Part a)
Electric field due to large sheet is given as


now the electric field is given as


Now acceleration of an electron due to this electric field is given as



Now work done on the electron due to this electric field



So work done is given as



Part b)
Now we know that work done by all forces = change in kinetic energy of the electron
so we will have



Answer:
Explanation:
Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point.They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. EXAMPLE: Solid ice melting into liquid
