Four charges are at the corners of a square centered at the origin as follows:
q at (-a, +a); 2q at (+a, +a); -3q at (+a,-a); and 6q at (-a, -a).
A fifth charge +q is placed at the origin and released from rest.
A) Find its speed when it is a great distance from the origin if a = 1.2 m, q = 1.2 C, and its mass is 1.1 kg.

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

True or false graphs must include scales that increase by the same amount

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
