Which question would be MOST appropriate to guide the scientific investigation?

A) What do birds eat?
B) What type of seeds do birds prefer?
C) Which seeds do our feeder birds prefer?
D) Which types of seeds do our feeder birds eat?

The field between two charged parallel plates is kept constant. if the two plates are brought closer together, the potential difference between the two plates either a) decrease b) does not change c) increase?

Asatellite with an orbital period of exactly 24.0 h is always positioned over the same spot on earth. this is known as a geosynchronous orbit. television, communication, and weather satellites use geosynchronous orbits. at what distance would a satellite have to orbit earth in order to have a geosynchronous orbit?
