Extra Credit (a).      A solid ball has a weight of 3.5N. When it is submerged in water (density of water is 1,000 kg/m3), it has an apparent weight is 2.7 N. What is the density of the             ball?                                                                                                           (2.5 points) (b).        The water in the plumbing in a house is at a gauge pressure of 190,000 Pa. What force does this gauge pressure cause on the top of the tank inside a water              heater if the area of the top is 0.7 m2?                                                                                   (1.5 points)

And then the temple was destroyed in 70 AD. Since this time there has been what is known as Rabbinic Judaism, which is the form of Judaism most people are familiar with and practice today.
