A140-g ball containing 4.10 * 108 excess electrons is dropped into a 110-m vertical shaft. at the bottom of the shaft, the ball suddenly enters a uniform horizontal magnetic field that has magnitude 0.300 t and direction from east to west. if air resistance is negligibly small, find the magnitude and direction of the force that this magnetic field exerts on the ball just as it enters the field.

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.
