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?

Q13.12 A planet (P) is moving around the sun (S) in an elliptical orbit. 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.

If 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!

Suppose a 5.9x1010 kg meteorite struck the Earth at the equator with a speed 2.0x104 m/s , as shown in (Figure 1) and remained stuck. Part A By what factor would this affect the rotational frequency of the Earth (1rev/day)? Express your answer using two significant figures.
