What does weight and mass have in common? In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the […]

This shiny appearance on the surface of some metals is called luster. What is the least ductile metal? gold can Is copper more ductile […]
When three different resistances R1 R2 and R3 are connected in parallel where R1 R2 R3 the equivalent resistance of the combination will be?
When three different resistances R1 R2 and R3 are connected in parallel where R1 R2 R3 the equivalent resistance of the combination will be? it is clear from the equation that value of R is less than R1 orR2 or R3=1 , therefore equivalent resistance of this combination is less than 1 ohm . When […]
