: A protein molecule in an electrophoresis gel has a net negative charge. The exact charge depends on the pH of the solution, but 30 excess electrons is typical. When released from rest, does the charged protein molecule move parallel (same direction) to the electric field or opposite to the electric field

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?

Why do different substances have diffrent properties

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
