Calculate the following centripetal accelerations as fractions or multiples of g and comment on the results: (a) The acceleration to- wards the Earth’s axis of an object resting on the Earth’s surface at 45◦ latitude. The Earth’s radius is 6378 km. (b) The acceleration of the Moon towards the Earth. The radius of the Moon’s orbit is 384399 km and its period is 27.3 days. (c) The acceleration of an electron moving around a proton at a speed of 0.007c where c is the speed of light in an orbit of radius 0.05 nm (the first Bohr orbit of the H atom)

Comment on the results of each of these recent experiments in light of the Old Friends hypothesis: a) A small group of Finnish children were matched at birth by age and relevant genotype, then followed to see if any developed autoantibodies typical of type I diabetes. Compared to matched healthy controls, the children who would develop T1D had markedly different gut microbiomes. Relative to those of matched healthy controls, rheir microbiomes were less diverse, more unstable, and became increasingly dominated...
