Consider the following transfer functions i)- obtain the inverse laplace transform of the following. ii) plot the step response for each case. (use matlab. t 20) 2e 0.5s 10 (t> =0) ] (s +4) (s + 2)2 aas (s +3) (s2 +4s+24.52) -(s2+s -1) t3)+3s+2) d) t4(s)-

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.

You can melt ice by applying pressure because the solid/liquid line has a slope.
