The bob (weight) at the end of a pendulum has a mass of 0.3 kilograms. the bob is pulled to position b and allowed to swing. it goes all the way to position c and swings back.

the potential energy of the bob at position b is > > 1.47 joules. if the maximum height of the bob is 0.45 meters when it swings back, joules of energy was transformed to thermal energy.
> > > > > use g = 9.8 m/s2 and pe = m × g × h.< < < < <

it's not 1.!

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
