1. An object floats in a beaker as shown. Assuming that the graduated cylinder was empty when the object was placed in the beaker and that the beaker was full to the level of the spout, what must be true?
O A The volume of the water in the graduated cylinder is equal to the volume of the objedt.
O B. The volume of the water in the graduated cylinder is greater than the volume of the object.
OC The mass of the water in the graduated cylinder is equal to the mass of the object.
OD. The density of the object is greater than the density of water.

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.
