How does the earth’s position in space, mass and atmosphere allow the planet to support life?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

When using the scientist method, which step comes last?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
