- The figure below shows the radial velocity of a star plotted as a function of time over the course of 20 days. Where is the planet located in its orbit on day 1 (the start of the graph)? 20 Orbit of star 10- Earth 10+ Time -20 Orbit of planet Radial VelocityQ3.2 The supergiant star has a surface temperature of about 2900 K and emits a power of approximately 4 x 1030 W. Assuming that is a perfect emitter and spherical, find its radius. (hint: Area of the sphere is A = 4πr²)The rate at which a nebular cloud rotates increases as the cloud collapses to form systems of stars and planets. Consider a small segment of a nebular cloud with a mass m of 1.9 x 102" kg, tangential velocity vinitial equal to 6.8 km s-1 located at an orbital distance rinitial = 2.5 x 10* km. After the cloud collapses, the same small segment is located at an orbital distance rinal = 3.2 x 10° km. Calculate the change of the rotational velocity, Ao, for the cloud segment, assuming perfectly circular orbits. Perform your work and report your solution using two significant figures.
