Ten identical lengths of wire are laid closely
side-by-side. their combined width is measured
and found to be 14.2 mm. calculate:
a the radius of a single wire
b the volume in mm of a single wire if its
length is 10.0 cm (volume of a cylinder =
tr’h, where r=radius and h= height).

can you find b

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 increase in density of a medium due to wave travel?

In a classical model of the hydrogen atom, the electron moves around the proton in a circular orbit of radius 0.053 nm. what is the electron's orbital frequency? what is the effective current of the electron?
