A mechatronics engineer works to automate the transfer of materials and goods, and the manufacturing process. Their tasks involve identifying areas for task automation, designing, developing and testing potential mechatronic devices, and implementing design solutions.
A typical tea bag has somewhere between a gram and two grams of stuff in it. If the entire contents were nothing but fructose, and that fructose completely dissolved when you made your tea, you'd consume between 4 and 8 calories (carbohydrates contain 4 calories per gram) per cup of tea -- so that's the ceiling.
Pour very hotwater over the tea bag. Dunk it up and down 2-3 times. Cover the tea container. Depending on how strong you want the tea depends on how long you keep the tea bag in the cup that is covered aout 5-7 minutes or steeped. Remove the tea bag and add lemon,or sugar, or cream.
