A 0. 260 kg particle moves along an x axis according to x(t) = -13. 00 + 2. 00t + 2. 00t2 - 6. 00t3, with x in meters and t in seconds. In unit-vector notation, what is the net force acting on the particle at t = 3. 40 s ? Give an expression for the (a) x, (b) y, and (c) z components

What property is a characteristic of a substance that can be observed and does not change the identity of the substance

In order of decreasing light-transmitting capabilities of materials, which is the correct sequence? a. transparent -> translucent -> opaque b. opaque -> transparent -> translucent c. opaque -> translucent -> transparent d. translucent -> transparent -> opaque

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
