A cyclist and his bicycle have a combined mass of 88 kg and a combined weight of 862.4 N. The cyclist accelerates at 1.2 m/s. After 2 seconds he reaches a speed
of 2.4 m/s. What is his momentum at this point?

O A. 211.2 kgm/s
O B. 36.7 kgm/s
OC. 1 05.6 kgm/s
OD. 359.3 kgm/s

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

If an atom contains 11 protons in its nucleus, predict the element with the atomic number and electronic configuration. will the number of electrons remain the same during the chemical reaction in such an atom? explain.
