How does the solar nebula theory help you understand the location of asteroids?

To calculate the angular momentum of an object, which properties of an object do you need to know?

Kepler 3rd law:    M1 + M2 = P2/D3   Jupiter’s moon Callisto orbits the planet at a distance of 1.88 X 106 km in about 16.7 days. If one year is 365 days, and if 1 AU is 1.5 X 108 km, calculate the mass of Jupiter in solar mass units. (Show your work)

Please answer the question and its subquestions entirely! This is one question with two subquestions. According to the official Bartleby guidelines, I am alowed to have up to two subquestion!   1) When an ice-skater spins and increases her rotation rate by pulling her arms and leg in, what happens to her kinetic energy?     It stays the same.     It increases.     It decreases.   a) A 0.400 kg mass, sitting on a horizontal frictionless surface, is attached to the end of a 0.750 m string. It is whirled around in a circular horizontal path. If the maximum tension that the string can withstand is 450 N, then what maximum velocity can the mass have if the string is not to break?     375 m/s     22.4 m/s     19.4 m/s     29.0 m/s b) A grinding wheel with a moment of inertia of 2 kg-m 2 has a 2.50 N-m torque applied to it. What is its final kinetic energy 10 seconds after starting from rest?     312 J     237 J     156 J     106 J

Our Solar System consist of two distinctly different types of planets. A. Describe how these planets differ in their general characteristics. B. Explain the cause of these differences

Consider Figure 13.23 in Tidal Forces. This diagram represents the tidal forces for spring tides. Sketch a similar diagram for neap tides. (Hint: For simplicity, imagine that the Sun and the Moon contribute equally. Your diagram would be the vector sum of two force fields (as in Figure 13.23), reduced by a factor of two, and superimposed at right angles.)

Ganymede is the largest of Jupiter’s moons. Consider a rocket on the surface of Ganymede, at the point farthest from the planet (as shown). Model the rocket as a particle. (a) Does the presence of Ganymede make Jupiter exert a larger, smaller, or same size force on the rocket compared with the force it would exert if Ganymede were not interposed? (b) Determine the escape speed for the rocket from the planet–satellite system. The radius of Ganymede is 2.64 × 106 m, and its mass is 1.495 × 1023 kg. The distance between Jupiter and Ganymede is 1.071 × 109 m, and the mass of Jupiter is 1.90 × 1027 kg. Ignore the motion of Jupiter and Ganymede as they revolve about their center of mass.

The orbital period of Charon is given in the chapter text. Given that the average distance of Charon from Pluto is 19,600 km, calculate the mass of Pluto. Assume the mass of Charon is negligible compared with the mass of Pluto. (Hints: Use the circular orbit velocity formula in Reasoning with Numbers 4-1; make sure to convert relevant quantities to units of meters, kilograms, and seconds.)

You are packing for a vacation on a planet orbiting another star that is much like the Sun. Why might you want some information about the planets orbit size and axis tilt to know what to pack?
