c. HCl in acetonitrile (CH;CN) H-CI н-с-с-N in d. HF in H20 H- F in H.

B The sum of vectors A and B is O O O

4. Consider again the situation given in Problem 1. (a) Find the center-of-mass of the system made up of m, and m,, taking the origin to be at P. (b) Draw a free body force diagram with the all of the mass (m, + m,) concentrated at this center-of-mass position. (c) Find the torque about P due to (m, + m2) concentrated at this center of mass position. How does this result compare to (d) in Problem 1? [We will make use of this technique often for certain types of future problems.]

Determine F1 and the angle of Theta. If the magnitude of the resultant force acting on the eyebolt is 800N and its direction measured clockwise from the positive x axis theta=30.

can someone solve d and e

can you answer d please? (d) Draw the velocity vectors,  and the resultant velocity vector at this time.

Someone drives 215 km west before turning to go 98 km southwest at 45°. How far are they from where they started? Express your answer using three significant figures. 293 km Submit Previous Answers ✓ Correct Part B In what direction are they from where the started, measured counterclockwise from due east?

Figure 2

please explain c）why B is point to east and why Force is pointing inward？？need 3D picture to prove this because I am so confused.What I get is force should pointing up and have no clue why B is east？B cannot be west？？？
