please show work? Question 31 (8 points) The radius of an atom of an unknown element is about 1.48x10° angstroms. Given that an angstrom is equal to 10-8 centimeters, use dimensional analysis to calculate the radius of this atom in inches. (Be sure to show all the conversion factors showing non-metric to metric units.) Please report your answer to the correct number of significant figures. Leave a space between the number and the unit.
Q 6: Four ions (Na+Na+, Cl−Cl−, Na+Na+, and Cl−Cl−) in a row are each separated from their nearest neighbor by 4.5×10−10 mm . The charge of a sodium ion is +e+e and that of a chlorine ion is −e−e. Determine the electric force exerted on the chlorine ion at the right end of the row due to the other three ions. (+x+x to the right) Express your answer with the appropriate units.
four ions (na, cl, na, and cl) in a row each separated from their nearest neighbor by 2.0x10^-10m. The charge of a sodium ion is +e and that of a chlorine ion is -e. determine the electric force exerted on the chlorine ion at the right end of the row due to the other three ions.
Help please show work Question 4 1 pts A charge of +8 micro coulombs is placed atx-Ocm,y-+14 cm, a charge of 4 micro coulombs is placed at x- 0 cm,y- 22 cm, a charge of +9 micro coulombs is placed at x6 cm y-0 cm, and an unknown charge is placed at at x- +17 cm, y 0cm. The angle of the total electric field at the origin is 298 degrees counter-clockwise from the positive x axis. What is the...
A surface encloses a +4.5 micro-coulomb charge, a -9.5 micro-coulomb charge, and an unknown charge. If the net electric flux through the surface is zero, what is the third charge in micro-coulombs? Include a negative sign if it's negative. please show your work so i understand
