A cube of water 10 cm on a side is placed in a microwave beam having . The microwaves illuminate one face of the cube, and the water absorbs of the incident energy. How long will it take to raise the water temperature by . Assume that the water has no heat loss during this time.
The raise of the water temperature is
A charge near its surroundings produces an electric field, which is a force. When other charges are brought near this field, they are subjected to this force. N/C (Force/Charge) is the SI unit for electric fields.
Now, Find value for :
Finally, find the values for :
The change in the quantity of water is .
