Each ATmega128 USART module has two flags used to indicate its currenttransmitterstate: the Data Register Empty (UDRE) flag and TransmitComplete (TXC) flag. What is the difference between these two flags, andwhich one always gets set first as the transmitter runs? You will probablyneed to read about theData Transmissionprocess in the datasheet (includ-ing looking at any relevant USART diagrams) to answer this question

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
