Q1. If 60 billion neutrinos per second rain down on one square cm of the surface of the Earth, how many neutrinos per second rain down on one square cm of the surface of Saturn? (Assume the Sun-Saturn distance is 10AU)
Q2. The flywheel is a solid disk with a mass of 64.0 kg and a radius R = 0.625 m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of 0.230 m. The tension Tu in upper (taut) segment of the belt is 170 N, and flywheel has a clockwise angular acceleration of 1.67 rad/s2. Find out the tension in the lower (slack) segment of the belt.
