PPH0075 Physics 1 Chapter 1 ASD 1/ 4 Tutorial 1: Physical Quantities 1. The mass of the planet Saturn is 5.64 x10 26 kg and its radius is 6.00 x 10 7 m. a) Calculate its density. b) If this planet were placed in a large enough ocean of water, would it float? Explain. 2. The planet Jupiter has an average radius 10.95 times that of the average radius of the Earth and a mass 317.4 times that of the Earth. Calculate the ratio of Jupiter’s mass density to the mass density of the Earth. 3. Show that the equation x = vt + ½ at 2 is dimensionally correct , where x is a coordinate and has units of length, v is speed, a is acceleration, and t is time. 4. The square of the speed of an object undergoing a uniform acceleration, a is some function of a and the displacement , s according to the expression v 2 = k a m s n , where k is a dimensionless constant. Show that this equation is dimensionally correct only if m = n = 1. 5. The period T of a simple pendulum is measured in time units and is T = 2 π l g / where l is the length of the pendulum and g is the free-fall acceleration in units of length divided by the square of time. Show that this equation is dimensionally correct.
