A bead is moving with a speed of 20 m/s at position A on the track shown in the figure. This track is friction-free, and there is no appreciable air resistance. What is the speed of the bead at point C?

Plzz worth 10 ! which statement about energy transformations is not true? a all forms of energy can be transformed into thermal b energy is never destroyed or created during transformations c potential chemical energy always transforms into kinetic d some thermal energy is always released during a transformation

Occurs when an energy source transfers heat directly to another subject space; an example would be an object becoming warm by sitting in the sunshine

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)
