In the figure below, m; = 10.5 kg and my - 4.5 kg. The coefficient of static friction between m, and the horizontal surface is 0.60 while the coefficient of kinetic friction is 0.30. (a) If the system is released from rest, what will its acceleration be?
(b) If the system is set in motion with my moving downward, what will be the acceleration of the system?

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

In which of the following cases is work being done on an object? question 2 options: pushing against a locked door carrying a box down a corridor pulling a trailer up a hill suspending a heavy weight with a strong chain
