1.The reference current for the DAC0808 is 2.0 mA. With the DAC output connected to the inverting input of an op amp with a feedback resistor of 5.0 kohms, what is the op amp output voltage with a digital input of 0x80.
2.Consider a prevailing lapse rate that has these temperatures: ground=21C, 500m= 20C, 600m= 19C, 1000m= 20C.If a parcel of air is released at 500m and at 20C, would it tend to sink, rise or remain where it is
