Aradio transmitting station operating at a frequency of 144 mhz has two identical antennas that radiate in phase. antenna b is 9.4 m to the right of antenna a. consider point p between the antennas and along the line connecting them, a horizontal distance x to the right of antenna a.

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.

What is a carrier wave and how does it affect what you hear on the radio

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.
