Two small beads having positive charges q1 = 3q and q2 = q are fixed at the opposite ends of a horizontal insulating rod of length d = 1.50m. The bead with charge q1 is at the origin. as shown in figure p23.11, a third small, charged bead is free to slide on the rod. (a) at what position x is the third bead in equilibrium? (b) can the equilibrium be stable?

q1 q2
+O+ x
|<x-->|
|<d>|

thats what the picture looks like lol! The + sign is a ball with a positive sign in the middle. And the O is a ball and doesnt show a + or a -

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.
