5. Given the following LTI continuous-time system below: x(t) h(t) y(t) h(t) = 1e$^{-t}$u(t) x(t) = cos 1t Note: $\frac{a}{j\omega + a}\delta(\omega - b) = \frac{a}{jb + a}\delta(\omega - b) = \frac{a}{\sqrt{a^2 + b^2}}\angle -tan^{-1}(b/a)\delta(\omega - b)$ a. Determine frequency response: H($\omega$) = Fourier transform of h(t) b. Using the determined H($\omega$) and Fourier transform method to find y(t)

Q7). A) Draw a graph of temperature vs heat (input) to water, starting at 0K for all 3 phases of water. Show the transitions between phases and mark where the heats of fusion and vaporization come in to play. B) Use this graph to draw a graph of the (molar) heat capacity of water covering all 3 phases, in SI units. Estimate the heat capacity of water in the 3 phases. (For liquid water: 1 calorie is defined as the heat needed to raise the temperature by 1C). And there are 4.18 Joules in 1 calorie. Justify your answers for the heat capacities.
