Does kinetic friction speed up or slow down an object? Therefore, which type of work is done by kinetic friction? What can you conclude about the change in an object's speed

relative to the type of work done on that object?

What is the fate of the electrons that interact with a specimen in an electron microscope?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

How will the system respond to a temperature increase?
