In this part of the experiment, you will be changing the speed of the bottle by dropping if from different heights. you will use the same mass, 0.250 kg, for each trial, so record this mass in table b for each velocity. then, calculate the expected kinetic energy (ke) at each velocity. use formula ke = 1/2mv^2,

where m is the mass and v is the speed. record your calculations in table b of your student guide.

How does the kinetic energy of a charge change as the charge moves under the effect of an electric field from higher potential to lower potential? a. the kinetic energy increases. b.the kinetic energy decreases. c.the kinetic energy remains the same. d.the kinetic energy is always zero.

Write the function getkthdigit(n, k) that takes a possibly-negative int n and a non-negative int k, and returns the kth digit of n, starting from 0, counting from the right

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
