The temperature in degrees Celsius (C) can be converted to degrees Fahrenheit (F) using the formula F(C)= 9 5 C k, where k is a constant. Find k, if to C=â’40oC corresponds F=â’40oF.

Asample of a gaseous substance changes into liquid. this process is called (blank) and it takes place when heat is (blank) a gaseous system

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
