In an inkjet printer, letters and images are created by squirting drops of ink horizontally at a sheet of paper from a rapidly moving nozzle. the pattern on the paper is controlled by an electrostatic valve that determines at each nozzle position whether ink is squirted onto the paper or not.
the ink drops have a mass m = 1.00�10? 11kg each and leave the nozzle and travel horizontally toward the paper at velocity v = 18.0m/s . the drops pass through a charging unit that gives each drop a positive charge q by causing it to lose some electrons. the drops then pass between parallel deflecting plates of length d0 = 2.00cm , where there is a uniform vertical electric field with magnitude e = 7.75�104n/c
1) if a drop is to be deflected a distance d = 0.310mm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop? assume that the density of the ink drop is 1000kg/m3 , and ignore the effects of gravity.
q = c

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

According to rutherford's nuclear theory, most of the volume of an atom is , so the volume of a hydrogen atom cannot be mostly due to the proton.according to rutherford's nuclear theory, the core of an atom (nucleus) contains most of of an atom and is , so the majority of the mass of a fluorine atom cannot be due to its nine electrons.according to rutherford's nuclear theory, the number of negatively charged particles outside the nucleus the number of positively charged particles within the nucleus, so a nitrogen atom has 7 protons and 7 electrons, while a phosphorous atom cannot have 15 protons and 150 electrons.word bank: dense, empty space, more than, mass, particles, the same as, less than, positively charged, negatively charged
