Find the ratio of the new/old periods of a pendulum if the pendulum were transported from Earth to the Moon, where the acceleration due to gravity is 1.63m/s2.Christian Huygens in the 1600’s invented the first clock which was small enough to fit in an ordinary room but much more accurate than the large tower clocks of his day. What was his big idea? Why does it work well on land but not at sea? (Ships would have to wait many years for an accurate on-board timepiece).What is the magnetic field strength and direction at point A for the figure shown?
