... The advantage is that they will from at large distances from the star, 104R*. CO J=1→0 lines are typically used The velocities at this range are much lower than the escape speed of the star, but they still indicate mass loss Knapp and Morris derived an expression for the CO mass loss rate in 1985 ...

... Explain why the spacecraft continues on its journey to the moon, even though the engines are turned off. There are no external forces acting on the spacecraft so from Newton’s 1st law of motion the object will maintain its velocity. (iv) Describe the variation in the weight of the astronauts as they ...

... Recall that gravity is a central force: the gravitational attraction between two bodies acts along the line joining them. In the formulation of equations 3.2 above, this means that the gravitational force on the mass µ acts in the direction ?r and therefore exerts no torque about the fixed centre. C ...
