Tami is doing experiments on three different unknown solids. she understands that treating them in different manners might result in changes to their bonding, and these changes may her identify unknowns. she treats samples of each solid four different ways: heating them, letting them cool, shining bright light on them, and hitting them once with a hammer. the chart shows what happened to each sample. answer quickly based on how they each acted in the trials, which substance(s) would most likely be metallic? a and b b c a and c

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?
