The magnitude of the tidal force between the International Space Station (ISS) and a nearby astronaut on a spacewalk is approximately 2GmMa/r3 . In this expression, M is the mass of the Earth, r=6.79×106m is the distance from the center of the Earth to the orbit of the ISS, m=125kg is the mass of the astronaut, and a=16m is the distance from the astronaut to the center of mass of the ISS. Part A Calculate the magnitude of the tidal...

A light string has its ends tied to two walls separated by a distance equal to three-fifths the length of the string as shown in the figure. An 18 kg mass is suspended from the center of the string, applying a tension in the string. What is the tension in the two strings of length L 2 tied to the wall? The acceleration of gravity is 9.8 m/s 2 . Answer in units of N

Two masses m1 and m2 are located a distance r apart and are initially at rest. Due to the attractive gravitational force, the two masses will move towards each other. Find the velocity of each mass when they are located a distance d apart. You are given G. (Answer: For mass m1: v1 = m2sqrt(2G(1/d-1/r)/(m1 + m2)))
