Angular Collisions
How much thermal energy is created in the process of disk 1 falling on disk 2 such that they reach a common final angular velocity? You do not need to worry about the gravitational potential energy because the initial separation of the disks is small.

- To calculate the angular momentum of an object, which properties of an object do you need to know?arrow_forwardI was able to determine the semi-major axis of Jupiter's moons by multiplying the angle of separation (in radians) with the distance between Earth and Jupiter. Briefly explain why this method works (i.e. why we are able to multiply by only the angle rather than sin(angle)).arrow_forwardPC Why are there two different types of planets in the solar system? O The amount of material available to form planets was greater in the outer reaches of the protoplanetary disk. O Rocky material could not collect and form planets beyond the asteroid belt. O The nebular cloud from which the solar system formed had very little gas. O The sun's heat allowed only rocky planets to form in the inner portion of the solar system. 1arrow_forward

As the planet moves from aphelion to perihelion, the planet's angular momentum A planet P follows an elliptical orbit. The sun S is at one focus of the ellipse. Perihelion Aphelion A. increases at all times. B. decreases at all times. C. decreases during part of the motion and increases during the other part. Kea There is nothing at the other focus. D. increases, decreases, or remains the same during various parts of the motion. E. remains the same at all points between aphelion and perihelion.arrow_forward
- Our understanding of the elliptical motion of planets about the Sun spanned several years and included contributions from many scientists. a. Which scientist is credited with the collection of the data necessary to support the planet's elliptical motion? b. Which scientist is credited with the long and difficult task of analyzing the data? c. Which scientist is credited with the accurate explanation of the data?arrow_forwardIf the rotational curve (orbital speed versus distance from center) of a spherically symmetric object is flat, what is implied about the mass density? A. It remains constant at all distance from center. B. It increases with distance from center. C. It decreases with distance from center. D. It remains zero far from the center because the distribution is essentially a point mass. Is the answer B? Orbital velocity is still the same as the distance from the centre increases. By Mr = v2r/G, Mass increases with increasing radius when velocity is kept constant. So, galaxies with flat rotational curves indicate they contain large amounts of dark matter, especially further out from the centre. Thank you for clarifying my understanding!arrow_forward1.
