summarize three ways a person can become better at scientific observation and explain why this is important

In a system, when potential energy decreases, then entropy also decreases. true false

Describe uniform velocity and variable velocity in short

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
