Homework Statement
A convex spherical mirror with a focal length of magnitude 24.0 cm is placed 22.0 cm to the left of a plane mirror. An object 0.300 cm tall is placed midway between the surface of the plane mirror and the vertex of the spherical mirror. The spherical mirror forms multiple...
I have encountered two separate review problems that have to do with finding a value for amplitude and I am really struggling with it.

Question 1-
A mass of 3kg is free to move on a horizontal frictionless surface and attached to a spring of k=15 N/m. It is displaced...
Thanks so much I think I have made sense of it and the concepts make sense to me, however, working through this I am getting results that are almost trivial - i.e. only 0.0003 kg of ice melts, the temp of the initial water remains practically unchanged and as a result of the mass of the new...
Homework Statement
5 kg of water at 60 degrees are put in contact with 1 kg of ice at 0 degrees and are thermally isolated from everything else. The latent heat of ice is 3.3x105 J/kg.
What is the change of entropy of the universe when 100J of energy are transferred from the water to the ice...
