Two parallel-plate capacitors, 7.0 µF each, are connected in series to a 18 V battery. One of the capacitors is then squeezed so that its plate separation is halved. (a) Because of the squeezing, how much additional charge is transferred to the capacitors by the battery? 21 Correct: Your answer is correct. µC (b) What is the increase in the total charge stored on the capacitors (the charge on the positive plate of one capacitor plus the charge on the positive plate of the other capacitor)?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
