models is shown below.
β’ A few of the positive particles aimed at a gold foil
seemed to bounce back.
O The colors of light emitted from heated atoms had
very specific energies.
Experiments with water vapor showed that
elements combine in specific proportions.

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
