Please help its my actual birthday lol A beam containing a mixture of helium isotopes enters a mass spectrometer. The beam then divides into two beams that each travel to a different point on the detector. Which property do the particles in the two beams have in common? A. each particle has the same mass B. Each particle is a helium atom, not an ion C. Each particle contains the same number of neutrons D. Each particle has the same initial velocity

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
