We have a circut element with terminals a and b. Furthermore, the element has v ab = 5V and iab = 2A. Over a period of 10 seconds, how much charge moves through the element? If electrons carry the charge, which terminal do they enter? How much energy os transferred? Is it delevired to the element or taken from it?
c) Find the output y(t) in response to the input x(t) = 6 u(t), where u(t) is the unit step function. d) Find the output y(t) in response to the input x(t) = δ(t) A linear system has the system response function H(s)= -7/(s+4)
The middle C string on a piano is under a tension of 970 N. The period and wavelength of a wave on this string are 3.82 ms and 1.18 m, respectively. Find the linear density of the string.
The number of cell phones recycled or refurbished instead of being sent to landfills is increasing by about 30% per year since 2004. In 2008, 5.5 million cell phones were recycled or refurbished. (a) Find an exponential model for the situation desc..

Write an instruction sequence to subtract the 6-byte number stored at $800-$805 from the 6-byte store a $810-$805, and save the result at $900-$905
On Earth, we assume normal room temperature is 293 degrees Kelvin. From this, we find that the power spectral density of thermal noise is -174 dBm/Hz. On Venus, the average surface temperature is 462 degrees Celcius.
