Setting up integrals- the hardest challenge for most people in this course! ) a wire has a uniform (constant)linear mas density λ (in units of kg/m). find its total mass if: (a) the rod is straight and extends along the x-axis rom x-0 to x-l, (b) the rod is bent into a circular arc of radius r, extending from 0-0 to 0-π. (c) explain why your answers in (a) and b) make sense, given that λ means mass per unit length. then repeat part (a) above, but now with the density not constant, but rather given by λ (x λο ( ) where λ,-const.

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r

With physics question #5? for any !

When doing scientific research ,the sources used should be ?
