[ a) Do you know formula for the mass moment of inertia for a ring? Is it K= rootof(Ic/m)?

Homework Statement For any flat object, located in the x-y plan applies to the equation: Ix+Iy=Iz where Ix,Iy,Iz is the moments of inertia about the x-axis, y-axis and z-axis. A flat circular coil has n windings and radius r. The mass of the coil is m. The coil is located in the x-y plan...

How can it become vectors, i don't understand it

How do i express that to make sense, i am really confused

I don't know how to add the vectors?

I can't take a screenshot, but how to calculate a torque of these charges and this rod.

Homework Statement A simple model of a polar molecule is a rod of length L with mass m where the charges q and -q is arranged at each end of the rod. The molecule is located between two capacitorplates where spacing is on potential difference between the capacitor is V. The molecule will have...

Homework Statement Three ions, each with a charge Q = e, located at the corners of an equilateral triangle with side length r midpoint of one of the sides of the triangle described M. a) Calculate the magnitude and direction of the electric field E of the three ions generated at point M...

b) yes that's it

I don't know how to express that to make sense

[b]1. Encountered with cue to a massive billiards ball, which is initially at rest, see figure uploaded. The ball has radius R and mass M. The queue hits with force F horizontally into the bale height h above the table, and the shock lasts a very short time Δt. It is reported that the moment of...
