A) develop a block diagram for a unity feedback control system having an open loop transfer function, 10 g(s)=+1.6s+4 4 marks process: b) obtain the closed loop transfer function for a given step change of magnitude of 4 to 2(a). 6 marks c) evaluate the rise time, percentage overshoot, maximum value of y (t), ultimate value of y(t), period of oscillation

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas. in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point

In saturated organic compounds, all the bonds between carbon atoms are called?
