Base your answers to questions 63 through 66 on the information and data table below.
A 1.00kilogram mass was dropped from rest from a height of 25.0 meters above Earth’s surface. The speed of the mass was determined at 5.0meter intervals and recorded in the data table below.
Using the information in the data table, construct a graph on the grid provided. Then pay attention to the directions given in the next four questions.
68. The diagram below represents a periodic transverse wave traveling in a uniform medium.
Sketch in a wave having both a smaller amplitude and the same wavelength as the given wave. 
Base your answers to questions 69 and 70 on the information and diagram below.
A 1.50 × 10^{–6}meterlong segment of an electromagnetic wave having a frequency of 6.00 × 10^{14} hertz is represented below.
69. On the diagram mark two points on the wave that are inphase with each other. Label each point with the letter P. 
Base your answers to questions 71 and 72 on the information below.
A 747 jet, traveling at a velocity of 70. meters per second north, touches down on a runway. The jet slows to rest at the rate of 2.0 meters per second^{2}.
71. Calculate the total distance the jet travels on the runway as it is brought to rest. Show all work, including the equation and substitution with units. 
Base your answers to questions 73 and 74 on the information below.
Io (pronounced “EYE oh”) is one of Jupiter’s moons discovered by Galileo. Io is slightly larger than Earth’s Moon. The mass of Io is 8.93 × 10^{22} kilograms and the mass of Jupiter is 1.90 × 10^{27} kilograms. The distance between the centers of Io and Jupiter is 4.22 × 10^{8} meters.
73. Calculate the magnitude of the gravitational force of attraction that Jupiter exerts on Io. Show all work, including the equation and substitution with units. 
Base your answers to questions 75 and 76 on the information below.
In a mercury atom, as an electron moves from energy level i to energy level a, a single photon is emitted.
75. Determine the energy, in electronvolts, of this emitted photon.
