Twenty- four specific objects transmit complex radio codes, including time signals traveling at the speed of light. You can contact at least 4 of the 24 objects at any time of day or night. The statement above refers to which of the following?1. GIS stations2. NTM's for chart use3. GPS satellites4. GNIS entries5. TIR scanning systems.

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x,y components step 4 step 5 step 6

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.

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?
