The drawing (not to scale) shows one alignment of the sun, earth, and moon. The gravitational force Fsm that the sun exerts on the moon is perpendicular to the force FEM that the earth exerts on the moon. The masses are: mass of sun = 1.99 % 1030 kg, mass of
earth = 5.98 x 1024 kg, mass of moon = 7.35 x 1022 kg. The distances shown in the drawing are rsm = 1.50 x 1011 m and rem = 3.85 x
108m. Determine the magnitude of the net gravitational force on the moon.

Waves are used in many practical applications to support work, entertainment, and health. one example is the use of ultrasound imaging to safely track the development of a growing fetus. what is a specific example of a practical application of waves in medicine, entertainment, safety, or other fields? provide a brief explanation of how the properties of waves are useful to that application.
