An airplane in the earth’s magnetic field can develop a voltage between its wingtips.

find this voltage if the plane has a velocity v = 250 m/s pointing due north, the earth’s magnetic field b = 0.5 g points 30◦ below due north, and the plane’s wingspan is 20 m.

which wingtip (left or right) is at a higher electric potential?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
