Acylindrical shell of surface charge density o and radius r is coaxial with the z axis. find the force per unit length (length along the z-direction) on the right half of the cylinder, where the right half is defined to be -r/2 < < ¢ < +t/2. do this two ways: (a) use the maxwell stress tensor (à la griffiths example 8.2) (b) use the force per unit area on a shell of charge, griffiths equation (2.51): 1 2 f = 2€0 1 2 1 в, в; 1 e, e tij 7dy в? )

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

What do you think car designers do if the damage caused by a crash test is too severe?

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.
