Jayden and Jordan used an iron bolt to build an electromagnet that will pick up 4 pins. How can they increase the strength of their electromagnet so that it will pick up 10 pins? Use a smaller iron bolt that has a smaller diameter.

Use fewer coils of wire around the iron bolt .

Use a bigger iron bolt where more coils can be added.

Use a smaller battery .

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.

The mantle is made up of which structural zones?
