Two charged particles are placed 2.0 meters apart. the first charge is +2.0 e-6 c, and the second charge is +4.0 e-6 c. what is the electrical force between the two charges?
(k = 9.0 e9 nm^2/c^2)
a. +1.8 e-2 n and it is repulsive
b. +3.6 e-2 n and it is repulsive
c. +4.5 e-2 n and it is attractive
d. +9.0 e -2 n and it is attractive

If the force on an object is in the negative direction, the work it does on the object must be [2 points a) negative. b) positive c) the work could be either positive or negative, depending on the direction the object moves

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
