In fig.25-45,c1 ! 10.0 mf, c2 20.0 mf, and c3 25.0 mf. if no capacitor can withstand a potential difference of more than 100 v without failure, what are (a) the magnitude of the maximum potential difference that can exist between points a and b and (b) the maximum energy that can be stored in the three-capacitor arrangement?

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

=force × distance a. work b. velocity c. pressure d. momentum

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
