The deflection plates in an oscilloscope are 10 cm by 2 cm with a gap distance of 1 mm. a 100 volt potential difference is suddenly applied to the initially uncharged plates through a 1100 ohm resistor in series with the deflection plates. how long does it take for the potential difference between the deflection plates to reach 60 volts?

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
