The first law of thermodynamics is as follows: ∆u=q-w , which means in a system is equal to added, minus done by the system. the units for these variables are in .

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 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

10. the kinetic theory of matter states that atomic particles will move if the temperature is above the freezing temperature of water atomic particles bounce off each other one time in their life atomic particles are constantly bumping off each other because particles are in direct contact with each other at all times all matter is made up of atomic particles which are in constant random motion
