A very long cylindrical iron rod of radius R is given a uniform longitudinal magnetization M, and then bent into a circle with a narrow gap of length w (this is essentially a toroid with a circular cross section from which a very small portion of.

Magnetisation M which will produce magnetic field at the center of the gap.

Explanation:

A bound surface current will flow around the square cross section in the direction perpendicular to the field.

This is like a torus and a square loop with a current flowing the opposite way.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

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 .
