Once a sound recording is made, how is the sound reproduced? by converting passive sound waves into active sound waves by converting sound waves into electronic signals by converting the electronic signals back into sound waves by speeding up the stored sound waves

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Based on the diagram of the electric field lines around the two spherical charges, what are the signs of the left and right charge respectively?
