A student creates an experiment in which a rnarble rolls down a ruler and into a piece of construction paper. (see picture).The construction paper moves 5 cm.
Which of the following changes to the initial conditions of the experiment would
be most likely to result in the construction paper moving the greatest distance?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
