A 1.00 cm high object is placed 4.70cm to the left of a converging lens of focal length 7.80cm. A diverging lens of focal length -16.00cm is 6.00cm to the right of the converging lens. Find the position and height of the final image! PLEASE HELP. DUE AT 11:59PM

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?
