four equal charges of +3microcolumb are placed at the four corners of a square that is 40cm on a side. Find the force on any one of the charge.​

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

Anne applies a force on a toy car and makes it move forward. what can be said about the forces acting on the toy car at the moment anne applies the force?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
