Three charges are fixed to an xy coordinate system. A charge of +16C is on the y axis at y = +3.1 m. A charge of -16C is at the origin. Lastly, a charge of +55C is on the x axis at x = +3.1 m. Determine (a) the magnitude and (b) direction of the net electrostatic force on the ...
The drawing shows an edge-on view of two planar surfaces thatintersect and are mutually perpendicular. Surface 1 has an area of 1.7 m^2, while surface 2 san area of 3.2 m^2. The electric field in the drawing is uniform andhas a magnitude of 250 N/C. Find the electrical flux th...
if a stock price starts at $61 goes up $3, goes up $2, goes down $1, down $4, goes down $5 what is the stock worth
One of the things that helped our understanding of radioactivity was the discovery of the electron in 1897. The 100th anniversary of this important discovery was celebrated widely in 1997. Explain why more people were aware of the 100th anniversary than of the original discovery.
how many states are surrounded by water?
The disk has mass 10kg and radius 0.25m. The rod has mass 5kg, length 0.5m and radius 0.05m. The rod is split down the middle and is hinged so that its two halves can lay flat against the disk. Suppose that the disk and rod are initially rotating at 3.0rad/s around the axis th...
When fifteen vehicles were observed at random for their speeds (in M.P.H.) on a freeway, the following data were obtained. 61 53 57 55 62 58 60 54 62 60 59 66 55 54 63 Suppose that from past experience it may be assumed that vehicle speed is normally distributed with standard ...
Thank you so much for your help! I was able to follow your steps very well! Much appreciated DrBob222!
For the strong acids find the [H3O]and [OH] in a solution that is .785% HNO3 by mass (assume a density of 1.01 g/ml). If someone could offer step by step instructions, that would be terrific!
A solution contains an unknown mass of dissolved barium ions. When sodium sulfate is added to the solution, a white precipitate forms. The precipitate is filtered and dried and found to have a mass of 258 mg. What mass of baium was in the original solution? (Assume that all of...
