the diagram represent a .20 kg sphere moving to the right along a section of a frictionless surface. the speed of the sphere at point a is 3.0 meters per second. approximately how much kinetic energy does the sphere gain as it goes form point a to point b

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
