A simple seconds pendulum is constructed out of a very thin string of thermal coefficient of linear expansion a 20 10 4 C and a heavy particle attached to one end The free end of the string is suspended from the ceiling of an elevator at rest The pendulum keeps correct time at 0 C When the temperature rises to 50 C the elevator operator of mass 60 kg being a student of Physics accelerates the elevator vertically to have the pendulum correct time The apparent weight in N of the operator when the pendulum keeps correct time at 50 C is 330x Find x Take g 10 m s O O O 2 5 4 2
