The powers of 2 ( 20=1 , 21=2 , 22=4 , etc) arise frequently in computer science. (For example, you may have noticed that storage on smartphones or USBs come in powers of 2, like 16 GB, 32 GB, or 64 GB.) Use np. arange and the exponentiation operator ** to compute the first 30 powers of 2, starting from 2^0. Hint 1: np. arange(1, 2**30, 1) creates an array with 230 elements and will crash your kernel.

During physical science class ben and jerry connected three identical lightbulbs in parallel to a battery where happens when ben removes one of the lightbulbs from it’s socket

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a.if the manual switch s is on, then the light l is on. b.besides the manual switch, there is a motion detector, m1, which activatesthis light.c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d.the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.
