Please answer all of them correctly and show your steps and proper reasoning. 2. Two spherical celestial objects, call them A and B have mass M, and M2 withradius R1 and R2 respectively. Initially they are at a distance d from eachother. Now solve the following problems.dAB. (a) What would be the gravitational acceleration on the surface of object A? You should ignoreB's presence in this case.(b) Find the escape velocity of object B. Again, ignore A's presence.(c) Now let's say these two objects, A & B start to move towards each otherdude to mutual gravitational attraction. Find the time when they willcollide with each other. Express you answer in terms of the given parametersand any universal constant.

The force that acts between two bodies that have mass is known as the gravitational force. This…

You stand in a flat meadow and observe two cows (Fig. P1.73). Cow A is due north of you and 15.0 m from your position. Clow B is 25.0111 from your position. From your point of view, the angle between cow A and cow H is 20.0, with cow B appearing to the right of cow A. (a) How far apart are cow A and cow B? (b) Consider the view seen by cow A. According to this cow, what is the angle between you and cow B? (c) Consider the view seen by cow B. According to this cow, what is the angle between you and cow A? Hint: What does the situation look like to a hummingbird hovering above the meadow? (d) Two stars in the sky appear to be 20.0 apart.
