Atank is connected to two pumps that feeds chemicals in the ratio of 1: 2. the mixture is agitated by a mixer for 30 seconds. after the mixing has stopped for 20 seconds. the discharge valve is opened. explain the process and the rationale of your design. (a) [5 marks] (b) draw up a system function table that identifies the inputs and outputs for th process. include the following in the table: . description status of sensors action of actuators plc addresses steps for the program activity of each step [5 marks] (i) write a plc program that will control the above batch process

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

it's all four options.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
