Consider a current flowing in wire made of aluminum (with density 2.702 g cm 3 and atomic weight 26.98 u). Assume that each atom contributes 3.5 conduction electrons.
What is the drift speed in a 2.5 mm -diameter aluminum wire carrying 25 A ?

if they have a finite resultant

pretty sure it's false

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
