A 60-m-long chain hangs vertically from a cylinder attached to a winch. Assume there is no friction in the system and that the
chain has a density of 10 kg/m. Use 9.8 m divided by s squared for the acceleration due to gravity. a. How much work is required to wind the entire chain onto the cylinder using the winch? b. How much work is required to wind the chain onto the cylinder if a 35-kg block is attached to the end of the chain?
C isotopes is the correct answer. Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number.All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
