Se introduce un electrón en un Campo Magnético de inducción magnética de 25 T a una velocidad de 5X105 m/s perpendicular al campo magnético. Calcular la fuerza magnética que se ejerce sobre el electrón.​

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Can someone me with questions 12 and 13 plz.

In the cathode ray tube experiment, j. j. thomson passed an electric current through different gases inside a cathode ray tube in the presence of an electric field. in which two ways did this experiment change scientists’ understanding of the atom?
