The voltage difference between two charged parallel plate conductors separated by a distance of 14 mm is 3 v. (a) what is the magnitude of the electric field between the plates? b) what direction does the electric field go? (c) what force would this electric field apply to an electron? (d) what force would this electric field apply to a proton? (e) how much work would be done on/by an electron that moves from the negatively charged plate to the positively charged plate? (f) how much work would be done on/by an electron that moves from the positively charged plate to the negatively charged plate?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
