In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres with masses of 1.20 kg and 12.0 g whose centers are separated by about 4.90 cm. Calculate the gravitational force between these spheres, treating each as a particle located at the center of the sphere. Need Help? Read It Master t

A satellite of mass 200 kg is launched from a site on Earth’s equator into an orbit 200 km above the surface of Earth. a. What is the satellite’s speed before it’s launched (in m/s)? (Hopefully, it’s moving along with the surface of the Earth as the Earth rotates.) b. What is the satellite’s speed in its orbit (in m/s)? (Remember there is only onespeed a satellite can have in order to maintain a stable circular orbit with agiven radius.) c. Assuming a circular orbit, what is the orbital period of this satellite? (In other words, how long (in hours) does it take for the satellite to complete one orbit?) d. What is the minimum energy (work) necessary to place the satellite in orbit,assuming no air friction? (Remember, work is the amount of energy added tothe system, and the total energy of the system is a combination of kinetic andgravitational potential energies.)

Please answer the following question(s): 1. A 104 kg person and their 10 kg dog are 12.5 m away from each other. If you approximate them both as perfectly spherical what if the attractive gravitational force between them? Use G = 6.67x10-11N-m²/kg² Enter to 3 significant figures ✔N F grav =

You know that the increasing speed due to gravity on the surface of the earth is 9.8 m/sec2, which the length of a incredible circle around the earth is 4 x lo7 m. You're given that the proportions of moon/earth distances across and masses are Dm Mm = 0.27 and = 0.0123 De Me respectively. (a) Compute the least speed required to elude from the moon's gravitational field when beginning from its surface. (b) Compare this speed with warm speeds of oxygen atoms at the moon's temperature which comes to 100°C. 59

Chapter 04, Problem 029 7 Your answer is partially correct. Try again. The drawing shows three particles far away from any other objects and located on a straight line. The masses of these particles are ma = 322 kg, mg = 589 kg, and to the right. Find the net gravitational force, including sign, acting on (a) particle A, (b) particle B, and (c) particle C. mc = 185 kg. Take the positive direction to be 0.500 m 0.250 m

Chapter 13, Problem 025 Your answer is partially correct. Try again. A solid sphere of uniform density has a mass of 2.9 x 104 kq and a radius of 2.5 m. What is the magnitude of the gravitational force due to the sphere on a particle of mass 8.1 kg located at a distance of (a) 4.8 m and (b) 1.1 m from the center of the sphere? (c) Write a general expression for the magnitude of the gravitational force on the particle at a distance rs 2.5 m from the center of the sphere. (a) Number Units (b) Number Units (c) Fon mk r, where k 0.000006300 N/m
