What will happen if the beadis slightly displaced from the point where it has no acceleration.Assume your hair grows at a rate of 1/44th of an inch per day. How fast is that in nm/s (nanometers per second)? Given that a typical atom is on the order of 1 x 10^(-10) m in diameter (see Table 1.3 on page 18 of the textbook), at approximately what rate does the protein synthesis that assembles your hair strands deposit atoms in units of atoms per second? I need the second question to be rounded to 1 significant digit.Two ships leave a port at the same time. The first ship sails on a bearing of 52º at 17 miles per hour. The second ship sails on a bearing of 322º at 22 miles per hour. a) draw a diagram showing the ships locations relative to each other after 2.5 hours. Annotate their bearings and speeds, respectively. b) how far apart are the ships after 2.5 hours?
