si HW 22 Another application of the principle of superposition is to reshape a charge by adding opposite charges to cancel out pre-existing charges. A square charge is made from a circular charge and a cornered-ring charge. Therefore, + The square plane charge has 1 m wide sides and the circular plane charge has a 0.5 m radius. Both have a constant charge density of 100 μC/m². The resulting subtraction produces a cornered-ring with the same charge density. The electric field from the square plane at the central axis is this. Ako tan (+4)* +2()²) The electric field from the circular plane at the central axis is this. 2nko a. What is the electric field due to this composite loop as a function of z? b. Graph the electric field and rank the three charged objects based on the magnitudes of their electric fields. c. What is the total charge on each of the three charged objects?

A rocket in space consumes fuel and oxidizer at the rate of 2.15 x 104 kg/s with an exhaust speed of 3.30 x 10 m/s. (a) Find the thrust (in N) produced by the rocket's engine. (b) Find the acceleration (in m/s2) of the rocket at liftoff from Earth's surface, if its initial mass was 3.00 x 10° kg. (Enter the magnitude.) m/s?

d. The Boolean equation y = ÃBC +Ã&ē + AB C TABC be implemented lesing only two - input NAND gates. The minimum number g gates requuêred is is to a) 3 (b, 4 (C, 5

Suppose that the floating point component of a processor is upgraded so that each floating point instruction takes only 1/4 as much time to execute as previously. (The execution times of all other types of instructions remain unchanged.) If the upgrade decreases the execution time of a particular program to 0.7 times what it was originally, what fraction of the original execution time must have been spent on executing floating point instructions? (Give your answer as a decimal number to at most two decimal places, e,g, 0.13.)
