Question

A boy took a piece of wire with a length of 20mm, diameter of 10mm and having a resistivity of 0.0785Ωm. He connected this wire to a cell and made a circuit. What do you think what must have been the potential difference if 5×10¹⁹ electrons flowed through the circuit in 10 seconds ? Also calculate the heat generated in this process and determine its power in kW. (Take π = 3.14)

Answer 1

Answer:

Difference Between Ocean, Lakes and Rivers. ... Oceans are large bodies of saltwater surrounding a continent. A river is a large flowing water body that empties itself into the sea. Lakes are large water bodies that areDifference Between Ocean, Lakes and Rivers. ... Oceans are large bodies of saltwater surrounding a continent. A river is a large flowing water body that empties itself into the sea. Lakes are large water bodies that are surrounded by land on all sides.

Answer 2

Given :-

The Approximate value of π is :-
