Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.7120 n when their center-to-center separation is 50 cm. the spheres e then connected by a thin conducting wire. when the wire is removed, the spheres repel each other with an electrostatic force of 0.1165 n. what were the initial charges on the spheres? since one is negative and you cannot tell whlch is positive or negative, there are two solutions. take the absolute value of the charges and enter the smaller value here. 9.77-10a-120 bemi a incorrect. thes 2/10 ersevious tries submn answer enter the larger value here. 6.60 x 10-6 c ou are correct.

Amass has an acceleration of 10- 2t. what is its velocity and displacement if it started at x- 4m and the initial velocity was 8m/s? at what time does it have 0 velocity? graph all graphs.

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
