The formula for work is
F*d
Therefore work=2.0N*3.0=6N*m
C. Acceleration is the rate of change of velocity. So at the top of the path, while the velocity is zero, the CONSTANT GRAVITATIONAL ACCELERATION is about 10 m/s^2 (9.8)
Acceleration = vf-vi /t
10-22/3=2.6m/s^2
Full outer shell of electrons, they are colorless and odorless ,their melting and boiling points are close together which gives them very narrow liquid range
