Answer:
a. Composition of Vector.
Explanation:
When a bird flies in the air, it stretches its wings into air and this movement helps it move in a certain direction. This is an example of composition of vector. Air strikes the wings in opposite direction and bird wing movement helps it move against the wind.
Answer:
yes.
Explanation:
because all websites use coding
Answer:
0.156 V
Explanation:
Analog to digital converter (ADC) is used to convert an analog signal into a digital signal.
Resolution of ADC means in how many parts the signal of interest can be divided.
The resolution can be found using
Q = Full scale Voltage range/2^M
Where the full scale voltage range is 10 V and M is the number of bits of the ADC.
Q = 10/2^6
Q = 10/64
Q = 0.156 V
Therefore, the smallest voltage difference that can be detectable by this ADC is 0.156 V
A wastewater plant discharges a treated effluent (w) with a flow rate of 1.1 m^3/s, 50 mg/L BOD5 and 2 mg/L DO into a river (s) with a flow rate of 8.7 m^3/s, 6 mg/L BOD5 and 8.3 mg/L DO. Both streams are at 20°C. After mixing, the river is 3 meters deep and flowing at a velocity of 0.50 m/s. DOsat for this river is 9.0 mg/L. The deoxygenation constant is kd= 0.20 d^-1 and The reaction rate constant k at 20 °C is 0.27 d^-1.
The answer therefore would be the number 0.27 divided by two and then square while getting the square you would make it a binomial.
I wont give the answer but the steps
