Suppose you made 5 measurements of the speed of a rocket: 10.2 m/s, 11.0 m/s, 10.7 m/s, 11.0 m/s and 10.5 m/s. from these measurements you conclude the rocket is traveling at a constant speed. calculate the mean, standard deviation, and error on the mean.

Let v1, v2, w be three linearly independent vectors in r 3 . that is, they do not all lie on the same plane. for each of the following (infinite) set of vectors, carefully sketch it in r 3 , and determine whether or not it is a vector space (i.e., a subspace of r 3 ). explain your reasoning

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
