Thea thin rod of cross section a extends along the x-axis from x = 0 to x = l polarization of the rod is along its length and is given by p z =ax^ 2 +b . a) calculate rho rho v and o 2 at each end. b) show explicitly that the total bound charge vanishes in this case.

Suppose you were asked to find the torque about point p due to the normal force n in terms of given quantities. which method of finding the torque would be the easiest to use?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

The energy produced as a result of this flow of electrons from atom to atom is called
