A long line carrying a uniform linear charge density +50. 0μc/m runs parallel to and 10. 0cm from the surface of a large, flat plastic sheet that has a uniform surface charge density of −100μc/m^2 on one side. Required:
a. Find the location of all points where an α particle would feel no force due to this arrangement of charged objects.
b. Choose an appropriate location of these points at a distance calculated in part A.

1. above the line
2. between the line and the sheet.

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

When an object is heated it contracts. a. true b. false

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
