Apoint charge q 6.5 x 10 12 c is placed at the center of a spherical conducting sh ell of surface of the conductor is directed radially outward and has magnitude 7.5 n/c. ner radius 3.7 cm and outer radius 4 6 cr ti e elect field use above the (a) what is the charge density (in c/m2) on the inner surface of the shell? (b) what is the charge density (in c/m2) on the outer surface of the shell? c/m2 (c) what is the net charge (in c) on the conductor?

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.

What is the speed of an object at a given moment?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
