Five metal samples, with equal masses, are heated to 200oc. each solid is dropped into a beaker containing 200 ml 15oc water. which metal will cool the fastest? a) aluminum b) copper c) gold d) platinum

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?
