A point charge of +10 °C is at (+3 m, O m) on the x-axis and a point charge of +10 C is at (-3 m, O m).

1) Determine the work required to assemble this charge
distribution

2) Find the magnitude of the electric field at a point (0,+3
m) on the y-axis.

3) A charge q - +1°C is placed at a point (0, +3 m) on the y-axis.
Find the magnitude of the force on the 1C charge.

Lin yao looks at the back of a spoon. how should she describe her reflection? upside down and smaller upside down and larger right-side up and smaller right-side up and larger

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
