Ernest Rutherford (the first New Zealander to be awarded the Nobel Prize in Chemistry) demonstrated that nuclei were very small and dense by scattering helium-4 nuclei from gold-197 nuclei. The energy of the incoming helium nucleus was 8.00\times 10^{-13}~\text{J}8.00ร10 โ13 J, and the masses of the helium and gold nuclei were 6.68\times 10^{-27}~\text{kg}6.68ร10 โ27 kg and 3.29\times 10^{-25}~\text{kg}3.29ร10 โ25 kg, respectively (note that their mass ratio is 4 to 197). If a helium nucleus scatters to an angle of 120^\circ120 โ during an elastic collision with a gold nucleus, what is the final kinetic energy of the helium nucleus?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 ยตc of charge distributed uniformly along its length, and the other carries - 2.50 ยตc 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?
