Question
A damped harmonic oscillator what kind ol change in its motion over time? The amplitude decreases until it reaches zero and the oscillator stops moving. The period increases over time until it moves infinitely slowly and stops moving. The frequency increases over time until it moves so fast that it appears to be stopped. The energy converts to entirely potential energy of the spring until it has zero motion. 20. A hot object and a cold object are placed into thermal contact. Which of the following describes what happens between them? Mark all that apply.Explanation / Answer

c = specific heat = 880
m = mass = 3 kg
Tf = final temperature
Ti = initial temperature = 10
Q = Heat = 87000 J
Using the equation
Q = m c (Tf - Ti)
87000 = 3 (880) (Tf - 10)
Tf = 44
