Section 7.2 Review En
1. Martha wakes up at 5:30 a. m. and cats a bowl of corn flakes. It's a nice
day, so she decides to ride her bicycle to work, which is uphill from her
house. It is still dark outside. Martha's bike has a small electric
generator that runs from the front wheel. She ſlips on the generator so
that her headlight comes on when she starts to pedal. She then rides her
bike to work. Draw a diagram that shows the energy transformations
that occur in this situation,

the total distance traveled by the car is

30km + 49km = 79 km .

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
